TaylorMade adds irons, balls to AeroBurner line

TaylorMade's AeroBurner line of metal woods, introduced in November, is about to go full service, including not only new irons but golf balls, too. Just like the metal woods, which also will expand to include a Mini Driver now, the irons and golf ball are focused on the average golfer and his search for distance. 

If TaylorMade’s current lineup of irons with face-flex-producing slots in both the sole and face are about making conventional irons yield more consistent distances across the entire face, its latest entry seems less subtle, or shall we say, more focused: The new AeroBurner is clearly dedicated to souping up the ballspeed on wider-soled, oversized, distance irons, with an additional focus on affordability. 

AeroBurner irons feature a new sole slot designed to help shots launch not only faster but higher. It's the fourth iteration of TaylorMade's sole slot technology that began with the RocketBladez irons in the fall of 2012. Unlike the slot (what the company calls a "speed pocket") on the RSi irons, it is not cut all the way through the back of the iron.

"This gives us more distance, but it also acts like a hinge to help shots launch higher," said Tomo Bystedt, TaylorMade's director of product innovation. The lowered center of gravity on the set also frees up the design to include stronger lofts for more direct energy transfer while maintaining higher launch.

Missing from the set is the additional face slots found in the RSi irons. The main reason, Bystedt says, is that the face slots were designed to make the compact face size more forgiving, not an issue for an oversized face like on the AeroBurner.

"When you look at face slots, you're looking at a technology that's essentially designed to make a club face play bigger than it is," Bystedt says. "It expands the boundary where the face starts to get rigid farther away from the middle. Going to a bigger face in this iron, it isn't going to have as much of a benefit. And the secondary reason obviously is cost. We think with all the other technologies of a thinner face and a higher moment of inertia that there are other ways to get forgiveness in this iron and keep it at a better price point."

The face includes the company's variable thickness design called inverted cone, which is specifically modified for the larger face area in AeroBurner. The shaping is shifted toward the toe to prevent shots from flying too far to the right, one of the learnings the TaylorMade team developed in understanding ultra-thin face iron designs like SpeedBlade and RSi. The AeroBurner face thickness is at 1.7 millimeters. For additional flexibility, the long irons are made of a 450 stainless steel and the short irons (8-SW) are made of 17-4. AeroBurner irons are $700 in steel, $800 in graphite and will be in stores March 18.

The extra speed idea for the AeroBurner line continues with the next installment of TaylorMade's Mini Driver franchise. With lighter materials and designs that enhance face flex at impact, there’s been an emergence of specialty low-lofted, oversized fairway woods (TaylorMade, Ping, Callaway) that are ideal for elite players on tighter driving holes and long shots into par 5s. 

But these new designs, with their extra loft and shorter shafts, may actually work better on most tee shots for average golfers, too. Their larger size makes them more forgiving than a traditional 3-wood, and their extra loft helps shots launch on a better angle. TaylorMade is bringing out its second version, the new AeroBurner Mini Driver ($280, available March 22). In addition to having a wide slot in the sole to provide extra give, the club has a slightly smaller size than last year’s model (for increased playability), a shallower face and a crown ridge and hosel fin to enhance aerodynamics. 

The head will be made of the same construction as the AeroBurner fairway woods, including a high strength nickel-cobalt-molybdenum martensitic steel alloy. The wider slot features a cut-through opening that's covered with a thermoplastic urethane insert. The cover maintains the flexibility of the open slot while preventing debris from lodging inside the opening. It also adds an element of vibration damping for better sound and feel. 

The slot aims to increase face deflection, particularly on low-face impacts and is designed to create a larger area of the face that approaches the USGA limit for spring-like effect. The head also continues TaylorMade's low-forward center of gravity location aimed to produce shots with reduced spin and higher launch.

The AeroBurner line also now includes two golf balls that will focus on average golfers in terms of playing requirements and price. The AeroBurner Soft ($20 a dozen, available March 6) is a two-piece model with a softer core and an ionomer cover. It’s designed for higher flight that should help the initial launch angle on tee shots as well as steepen the landing angle on short approach shots. There’s also the AeroBurner Pro ($27), a three-piece ball that features an intermediate mantle layer and a thin, resilient cover designed for softer feel than traditional ionomer-covered balls.

Cobra shows it's got better players in mind, too

Cobra may have had notable success in making clubs for average golfers who need help getting the ball in the air as easily as possible, but it isn’t taking a pass on players with a more sophisticated array of demands. 

It’s certainly made the case in drivers and fairway woods with the Cobra Fly-Z+, and now the company is bringing the same better player focus to the iron game. Two new forged irons, the Fly-Z Pro and the Fly-Z+, will be in stores this week and the emphasis is on precision and shot-making in a compact, better-player-friendly shape and sole width.

A key element in both irons is the five-press forging process. That methodology is designed to limit the post-forging hand grinding and improve the consistency of the internal structure of the carbon steel from head to head, as well as better control of the head weights. Furthering the precision are a CNC-milled face and grooves.

The Fly-Z Pro is a traditionally-shaped blade that progresses into a slight cavity back through the set into the longer irons. The short irons (9-PW) feature a traditional muscleback look, while the middle irons (7-8) have a slight cavity low in the back and the long irons utilize a dual cavity shape in back. Developed with input from Cobra staff player Rickie Fowler, the irons include a tungsten plug in the toe that helps reposition the center of gravity more in line with the center of the clubface. Fowler’s AMP Cell Pro irons were specially retrofitted with this feature last year. The Fly-Z+ is a multi-piece design that includes a milled undercut in the back cavity on the 3- through 8-iron for improved off-center hit forgiveness. The longer irons (3-7) also feature tungsten in the sole to help position the center of gravity in line with the center of the face. A thermoplastic urethane insert rests in the undercut and an aluminum badge encased in to create a softer feel. 

Both sets will be in stores March 1 ($900, for an eight-piece set, True Temper Dynamic Gold for Fly-Z Pro, KBS Tour for Fly-Z+).

Callaway's "X" line gets its broadest launch with XR's nine new products

xr-driver-sole-b.jpgCallaway’s “X” family of products goes back to the late 1990s and the introduction of the X-12 irons 17 years ago. Back then, the story was the revolutionary thinned out cavity construction and extreme low center of gravity on the cavity back oversized iron. Big news that almost immediately set sales records for the company.

But there may never have been a broader range of new technologies in the history of the X family than there is this year.

Callaway today announced nine new products under the new XR moniker, including two drivers, three fairway woods, two hybrids and two irons. The theme consistently across each category seems to be speed. Whether it’s the lighter face in the XR drivers or the metalwood-like face cup on the traditionally-shaped, cavity XR irons, Callaway’s engineers are chasing new ways for golfers to produce both more ballspeed and, in some cases, more clubhead speed. 

But the breadth of offerings (at least two styles in the driver, fairway wood, hybrid and iron offerings) also seems focused on helping individual golfers better dial in the size and shape of head that’s going to produce the best results for them.

Evan Gibbs, Callaway's senior manager of product performance in metalwoods, was referring to the new XR fairway woods, but his summary could easily apply to the whole XR family: “We tried to understand where golfers use these clubs, how they use them and how to most effectively design a club for that situation.”

All clubs in the XR line are expected to begin to be available in shops by Feb. 20.

XR/XR Pro drivers
The natural question with Callaway introducing its fourth and fifth drivers since August is how could it be any better. But Callaway is not shy about making its case with the new XR and XR Pro drivers ($350/$400). First, there’s a move toward improved aerodynamics. The XR features a pair of distinct speed steps at the front part of the crown designed to reduce drag. It also helps boost swing speed potential through a lighter overall weight (just TK grams on the XR model). According to Gibbs, the lighter weight features draw bias to help average golfers square the face and fight a slice. 

Second, the face on the XR is 10 percent lighter, and the center of gravity (CG) is 17 percent lower than last year’s X2 Hot. Similar to this fall’s Big Bertha Alpha 815 drivers, it utilizes a ribbed structure toward the front of the crown and sole to help increase the area of the face that yields the fastest ball speeds. Third, the XR Pro uses a forged composite crown to produce the lowest CG of any Callaway driver ever. 

“The advantage of having forged composite is you can create very aerodynamic shapes, which typically means the crown apex is higher and further aft, without paying a cg penalty,” Gibbs says. “You have such a lightweight material that you can pull the crown up and shape it to be aerodynamically efficient without the cg going too high.”

Each of the four lofts in the standard model (9, 10.5, 12 and 13HT) and two in the Pro (9, 10.5) include Callaway’s eight-way adjustable loft hosel. The hosel allows the user to reduce loft by one degree or increase it by one or two degrees and then also independently alter lie angle. One further benefit of the XR driver is its lighter weight. 

XR/XR Pro fairway woods, hybrids
The distinct shape differences in both the XR fairway wood and hybrid lines grew from how players of different ability levels use the clubs. The fairway wood line includes three varieties (standard, Pro and 3Deep) and the range accommodates 10 lofts, including the only stock 11-wood from a major manufacturer ($230 for the XR, $240 for the XR Pro and XR 3Deep). 

“The standard XR was designed with an emphasis put on performance and utility from the fairway,” Gibbs said. “The Pro version was designed with more of an equal usage from the tee and fairway in mind. And the Deep version was designed with an emphasis of performance off the tee.” 

The club’s primary technology is a redesigned cupface that’s thinner and lighter to help boost ballspeeds and lower the CG. The internal weighting updates the wave-like feature toward the front of the sole, pushing more weight forward while still freeing up the area low on the face. This helps to reduce spin and improve ballspeeds for shots hit low on the face. 

The XR and XR Pro hybrids offer similar differences to the fairway woods in size and shape (the Pro is decidedly more compact to appeal to better players), and the cupface and low CG design have been updated. Gibbs says the CG on the XR is 46 percent lower than the X2 Hot, while the CG on the XR Pro is the lowest ever for a Callaway hybrid. 

XR/XR Pro irons
The problem with creating irons with face structures that attempt to flex like drivers is that they end up looking and feeling more like drivers than irons. That means hollow construction irons that often are oversized and excessively wide-soled. 

Callaway’s effort with the XR iron line is to incorporate the flexibility in the face produced by its cup face design but wrap the technology in a more traditional, cavity-back iron shape. Both the XR and XR Pro feature a two-piece construction where the face cup wraps over the entire perimeter of the face and is fused to the sole and back of the iron. This allows for more control of how thin the face can be made to improve rebound across a greater area.

“The benefits of the 360 face cup that we see in an iron are very similar to what we see in a fairway wood or a hybrid,” said Luke Williams, senior director of  product strategy in fitting and irons. 

Within the cavity is an internal wave-like structure that improves performance on low-face impacts and lowers the center of gravity. The XR ($800) features more offset, while the XR Pro ($900) uses a thinner top line and narrower sole.

Wilson Golf leans on tour-player input with design of its new FG Tour V4 irons

Although Wilson Staff irons might not get the first look from golfers, the FG Tour V4 has some meaningful technological achievements. Gone is the boxy toe of recent Wilson models, replaced by a rounder shape and a sole grind that matches that preferred by staff player Kevin Streelman.

loop-wilson-FG-iron-300.jpgThe irons are forged from a soft 8620 carbon steel and have an 18-gram tungsten weight in the sole of the 3- through 7-irons. The idea is to help players hit shots with irons that are often the toughest to launch and stop shots on greens using a steeper trajectory rather than relying on spin.

The upper portion of the face area, where impacts are least likely to occur, was thinned by 11 percent with the saved weight moved lower and to the heel and toe areas to assist mis-hits.

The irons ($900) come standard in a 4-iron through gap wedge set and will be available Jan. 15.

Cleveland's latest take on the might of light

CG_BLACK_DRIVER3.jpgAt the elite level, it seems golf is increasingly becoming a power game. That’s all well and good when you have plenty of power to burn. For average golfers, though, power often isn’t so easy to come by. In fact, Cleveland Golf estimates that average golfers, particularly seniors and recreational players, may have swing speeds 15 or more miles per hour slower than the average on the PGA Tour (113 miles per hour).

One solution that’s been offered successfully in Japan for years is clubs with lighter than traditional overall weights. Most notable has been the XXIO brand of drivers launched by Dunlop Sports, which repeatedly have been that country’s top seller, pushing well below 290 grams in total weight. That’s a good 10 percent below the weight of many typical drivers played in the U.S. 

Cleveland, whose parent company is Dunlop Sports, has been developing lighter overall weight golf clubs since the beginning of this decade with clubs like the original CG Black, a driver introduced in 2011 that weighed just 265 grams or about 60 grams lighter than some of the leading drivers in the game at the time. Now comes the new family of CG Black metalwoods and irons, all aimed at average golfers and all featuring an ultralight platform. It’s what Cleveland’s engineers call an emphasis on “increasing the average golfer’s ease of swing.”

Says Jeff Brunski, director of research and development at Cleveland Golf/Srixon, “We looked at the typical average golfer’s swing and ball-flight inefficiencies, and targeted our technologies specifically geared toward them.” 

The new CG Black driver weighs five grams less than its predecessor, is the lightest driver on the market from a major company and features the concept of lower “swing MOI.” This refers to the moment of inertia of the entire club from head to the butt of the shaft. Instead of a measurement of how stable the club head is on an off-center hit, swing MOI is a theory having to do with how little resistance a particular club might have to being moved. For example, a sledgehammer might have a high swing MOI in that it requires more force to move it faster, but a 260-gram driver like the new CG Black might have a lower swing MOI, making it easier for those less skilled or strong to manipulate it. The concept of swing MOI was also front and center with the recent introduction by Wilson of its adjustable D200 SuperLight driver, which weighs just 268 grams. 

The new CG Black ($350; 9, 10.5 and 12 degrees), which is not adjustable, features the lowest swing MOI of any 460cc driver in company history, and includes a Golf Pride Tour 25 grip that is less than half the weight (25 grams) of a typical rubber grip. 

The CG Black line also includes a sub-300-gram family of fairway woods ($200; 15, 16.5, 18, 20, 23 degrees), which features a 24 percent lighter face that allows the weight to be distributed for higher clubhead stability at a lower total weight. The CG Black hybrids also are about 25 grams lighter than typical hybrids and come in a range of five lofts ($170; 17, 19, 21, 23 and 25 degrees). 

Rounding out the new CG Black line is a mixed set of irons ($700) that includes hollow hybrid-like long irons with 1770 high-strength steel faces, two-piece middle irons with a high-strength steel face insert and traditional one-piece cavity back short irons. It features a center of gravity slightly farther back and lower than last year’s super game-improvement 588 Altitude irons.  

The full line of CG Black clubs is scheduled to arrive in stores next week.

TaylorMade's new irons have slots--on the face

RSi 1Face.jpg
Right away, the new RSi family of irons from TaylorMade look different. With vertical slots framing the hitting area of the face, TaylorMade is suggesting the thinking about iron design needs to change.

RSi 13qtr.jpg
“Gone are the days in irons when you worry about just moving the center of gravity or raising the moment of inertia five percent,” says Bret Wahl, vice president of R&D for irons at TaylorMade. “There are a lot of other complex variables that you’re considering, and they all factor in getting faster ball speeds across the face of an iron.” 

What Wahl is talking about, and what he and his team at TaylorMade have been talking about since the early days of the r7 CGB Max irons nearly a decade ago, is the idea of creating an iron face that flexes at impact the way a driver does. Specifically, it’s about creating a larger area of the face that’s “unsupported.” 

To that end, it’s not just about building a deeper or larger cavity, Wahl says. Instead, it’s using a cut-through opening in the sole and now similar openings on the heel and toe side of the face in an effort to make it flex more not just on center shots but on mis-hits. TaylorMade says their research shows 78 percent of iron-shot impacts occur low on the face (heel and toe) and 61 percent are towards the toe (both low and high).

RSi 2-3qtr.jpg
To combat these mis-hits, TaylorMade built the RSi line with face slots in the 3- through 8-iron and sole slots in the 3- through 7-iron. Each opening is cut fully through the iron, and each slot is filled with compounds designed to allow the metal to flex. 

The RSi line (available for demo today, for purchase Nov. 14) includes RSi 1 (a game-improvement iron designed as TaylorMade’s longest iron); RSi 2 (an iron shaped like a cavity-back players iron but with enhanced distance capability); and RSi TP (the most compact iron, but still featuring a cavity back and face and sole slot technologies). 

RSi 1 ($800) features the thinnest face ever on a TaylorMade iron, just 1.5 millimeters thick at the extremes. It has the widest sole and the deepest undercut cavity of the three new irons, but like each it features TaylorMade’s proprietary variable face thickness design known as “inverted cone”.

The more compact RSi 2 ($900) is cast of a high-strength steel alloy (Carpenter 450) in the 3- through 7-irons, while the short irons feature forged faces and the gap wedge is forged entirely. The 3- through 5-irons also utilize tungsten in the toe to lower the center of gravity for help in launching shots higher. 

The RSi TP ($1,200, available Jan. 15) mixes one-piece forged short irons with a two-piece design in the 3- through 7-irons. The two-piece middle and long irons use a forged 1025 carbon steel face and neck that is plasma welded to a 431 stainless steel piece that forms the back cavity and sole slot.

Srixon took a material made for car engines to strengthed the face of its new irons

loop-srixon-Z545-6-Iron-350.jpgEven with irons, it's rare to find a player who isn't looking for distance. Of course, that often has meant giving up a classic, compact forged iron to find extra length. But recent introductions from Mizuno, Nike, Callaway and TaylorMade, among others, have paired a high-strength-steel face insert with a compact stainless-steel body to help boost distance.

Srixon is joining the game with its Z 545, which has a face insert made of a SUP10 steel, a material developed for automobile engines that's 10-percent stronger than traditional 17-4 steel.

The long and middle irons also make use of tungsten in the toe to position the center of gravity more in line with the center of the face.

The Z 545 ($1,000) will be available in November.

Wilson Staff pushing lightweight limits

The theory about making clubs lighter is less weight should make the club easier to swing faster. But it’s not that simple. “Lightweight is fairly easy to do,” says Michael Vrska, director of innovation for golf clubs at Wilson Staff. “The key is to how you use the limited available mass.” 

Still, the company is pushing the limits of lighter weight. Fueled by ultralight shafts and grips and an adjustable driver head that is the lightest in the industry, Wilson unveiled its D200 line of woods and irons this week by talking about how to make lightweight clubs work for more golfers. The D200 line includes a driver with a total weight less than 270 grams, fairway woods and hybrids that use 49- and 54-gram shafts and a superlight super game-improvement iron that redistributes 48 grams to the heel and toe to improve stability on off-center hits.

Vrska says the most important aspect of the company’s new D200 driver is not just its lighter overall weight-just 268 grams-but something called club moment of inertia. While the MOI most golfers think of has to do with how stable the club is on an off-center hit (higher is generally better), the thinking on club MOI is just the opposite. Club MOI has to do with how resistant an object is to some force causing it to move (like say a golfer trying to swing it). A lower club MOI, theoretically, might mean a club is easier to swing faster. Vrska says the club MOI on the D200 is the lowest on the market. The D200, which also features a thinner, webbed, variable thickness crown through the use of a chemical etching process, also is the lightest adjustable driver in the game with a head weight of just 189 grams or about 15 grams lighter than most adjustable driver heads today. Each of the three lofts (9, 10.5, 13; $300) can be adjusted up or down one degree, and put in a draw setting.

The face size on the D200 also has been increased by 9 percent and redesigned compared to the D100. The thickness of the lower perimeter of the face has been decreased by 12 percent to further improve face deflection on off-center hits. 

Also fueling the lightweight design is a special 25-gram Golf Pride grip and a 44-gram UST Mamiya Elements Chrome shaft. 

The line includes fairway woods and hybrids with Carpenter 455 steel face inserts. Vrska says the high-strength Carpenter 455 is able to made 20 percent thinner than traditional 17-4 steel and 13 percent thinner than some Chines steels labeled “455.” The thinner face helps create the highest spring-like effect readings for Wilson’s fairway woods and hybrids in its history. Both the fairway woods and hybrids have extended low heel and toe regions for a 5 percent larger face area. The fairway woods (15, 18, 21 degrees; $250) use a 49-gram UST Mamiya Elements Chrome shaft, while the hybrids (17, 19, 212, 25, 28, 31 degrees; $180) feature a 54-gram version. Both use the 25-gram Golf Pride grip found on the driver.

The D200 irons continue the lightweight theme, but while the saved weight is repositioned in the heel and toe, it’s how the weight is saved in the head that is especially interesting. The design features extending the same thickness of the already thin face around the leading edge and into the front part of the sole. The sole is thinnest on the longer irons and the weight is moved farther back in the cavity. As the lofts progress higher, the face-to-sole transition area isn’t as thin and the weight moves forward to control trajectory and feel. The saved weight, almost 50 percent of the club’s total mass in the 4-iron, is repositioned to the heel and toe to lower the center of gravity and to raise the head’s MOI by 9 percent, compared to the D100.

The D200 irons ($600 steel, $700 graphite) come with an 85-gram steel option and a 59-gram UST Mamiya Elements Chrome graphite option. 

All of Wilson’s D200 clubs will be in stores Jan. 16.

Callaway's Big Bertha iron employs driver design

Whether it be thinner, variable thickness faces or lowered centers of gravity, the goal always has been to imbue the new modern iron with the same high-launch, low-spin ballflight capabilities found in modern drivers. Now, Callaway is bringing the thoroughly wood-like technology of a cupface that covers the full, 360-degree perimeter to the latest version of its venerable Big Bertha iron line. 

A cupface, which is also found in Callaway’s latest X2 Hot fairway woods and hybrids, features a face whose perimeter wraps around the topline and sole. By moving the inflexible welded section off the face, the area of the face that has the highest flexibility (the so-called “sweet spot”) can expand. With some faster-faced irons, a special high-strength steel is welded as an insert within the area of the face. On the Big Bertha iron, that weld line circles around the topline and sole to create a more resilient face. 

The key, says Alan Hocknell, Callaway’s senior vice president of research and development, is controlling not just the thickness of the face. 

“With our fairway woods and hybrids, we learned a lot about face cups and how to make the area immediately adjacent to the face so it could take part in the impact to improve the flexibility of the face,” Hocknell says. “That annulus is important to us for making it thin and creating extra ballspeed as a result of extra flexibility.”

The irons are said to produce faster ball speeds through several other aspects. The 17-4 stainless steel uses a special heat treatment process to make it thinner. Also, the internal structure of the head features the lowered, forward weighting found in Callaway’s X2 Hot fairway woods to create lower-spinning higher-launching shots. There’s also a new, iron-specific variable thickness construction on the face design to create more face rebound at impact for both higher ball speeds on center shots and less loss of ball speed on mis-hits. Says Hocknell, “We don’t want to just improve flexibility randomly, we need to control that all over the face.”

Also, in terms of playability and aesthetics, the Big Bertha irons utilize progressively wider soles as the iron lofts get stronger. Also, the blade lengths and  sole widths stay consistent with the game-improvement irons category. 

Callaway also announced today the availability of its new Big Bertha hybrid. The design features an adjustable hosel that can accommodate four distinct lofts in each head (minus-one degree, neutral, plus-one and plus-two degrees) with two loft angles. Featuring a slightly larger profile than the company’s X2 Hot hybrid, the Big Bertha is Callaway’s first adjustable hybrid. It’s available in five lofts (19, 22, 25, 28 and 31 degrees) for $250.

Available Oct. 17, the Big Bertha irons ($1,000 in steel or $1,300 as a combo set with the new adjustable Big Bertha hybrids) employ this 360-degree cupface design throughout the entire set, which runs 3-iron through sand wedge.

Mizuno touts thin faces for faster ballspeed in its JPX-850 irons

Forged irons have long been what Mizuno is known for, but its greatest sales success recently has been with flexible-face cast irons.

loop-mizuno-jpx850-cast-iron-518.jpgThe new JPX-850 is the company's next step in pursuing a distance iron in a compact shape. "This is our thinnest multi-thickness iron face ever," says David Llewellyn, Mizuno's golf R&D manager. "But we've also saved weight with the acoustic badge while maintaining our standards for feel."

Other upgrades include thinner pockets inside the topline and sole for better off-center hits.

Like all its new irons, Mizuno offers any custom steel shaft at no extra charge. The JPX-850 retails for $800.
