Number of Wins: SixPlayers: Zach Johnson (BMW Championship), Bill Haas (AT&T National), John Merrick (Northern Trust Open), Adam Scott (The Masters and The Barclays), and Woody Austin (Sanderson Farms Championship)Tech Talk: The forged face insert is thinner and lighter than previous TItleist models to increase ball speed. To make workability easier, the center of gravity was moved forward. This driver is adjustable in 16 different ways, which allows loft and lie angle to be adjusted independently.
Number of Wins: FivePlayers: Henrik Stenson (Deutsche Bank), Justin Rose (U.S. Open), Brian Gay (Humana Challenge), Dustin Johnson (Hyundai Tournament of Champions), and Boo Weekly (Crowne Plaza Invitational)Tech Talk: There are three ways to adjust this driver. First, the hosel has 12 settings to alter loft (ranging from eight to 12 degrees). The rotating soleplate can be set to seven different face-angle positions. And lastly, the moveable sole weights can be manipulated to change between draw and fade bias. There are a total of 168 different settings.
Nike VR Tour
Number of Wins: FourPlayers: Tiger Woods (WGC Cadillac Championship, Arnold Palmer Invitational, The Players Championship, and the Farmers Insurance Open)Tech Talk: The pear-shaped head has a deep face and a variable compression channel in the sole. The channel is to improve the way the face flexes on off-center hits for enhanced ballspeed on mis-hits.
TaylorMade RocketBallz Stage 2
Number of Wins: 2Players: Martin Laird (Valero Texas Open) and Ken Duke (Travelers Championship)Tech Talk: The RBZ Stage 2 utilizes two key design features to improve ballspeed. First, the face is a larger than the original RBZ , (4,100 square millimeters) to enhance the area producing the most face deflection. Second, the crown utilizes a waffled internal structure to get as thin as 0.4 millimeters and save weight. The weight is then redistributed low and forward in the sole to improve energy transfer. Although neither Laird or Duke played the club this way, the stock shaft also is a superlight 50 grams. The hosel has 12 adjustable settings that alter loft by plus or minus 1.5 degrees.
Number of Wins: TwoPlayers: Michael Thompson (Honda Classic) and Derek Ernst (Wells Fargo)Tech Talk: The crown is sleeker on this driver to improve aerodynamics. Tungsten sole weights in the heel and rear of the sole put the center of gravity low and back from the face for improved stability on off-center hits. It is designed to sit neutral.
Bridgestone J40 (430)
Number of Wins: TwoPlayer: Matt Kuchar (World Golf Championships—Match Play and The Memorial)Tech Talk: The crown wall is thin, and the saved weight is repositioned to the perimeter for improved forgiveness. There is a stainless steel screw weight positioned in the heel to lower the center of gravity for reduced spin.
There was a tie on the LPGA for the winningest driver: Inbee Park won with the XXIO7 six times, and three players combined to win six times with the TaylorMade R1.SRIXON XXIO7Number of Wins: SixPlayer: Inbee Park (Honda LPGA Thailand, Kraft Nabisco, North Texas Shootout, Wegmans LPGA Championship, Walmart NW Arkansas Championship, and the US Women's Open)Tech Talk: The center of gravity is deep to produce a higher launch angle. Weight was added to the heel to shift the center of gravity closer to the shaft to make it easier to square up the clubhead at impact. The variable thickness face employs a high-strength, low-density titanium with the thinnest sections extending to the leading edge for improved off-center hit ballspeeds.TAYLORMADE R1Number of Wins: SixPlayers: Stacy Lewis (HSBC Women's Champions, RR Donnelly Founders Cup, RICOH Women's British Open), Beatriz Recari (Kia Classic and the Marathon Classic), and Ihee Lee (Pure Silk-Bahamas LPGA).
