Gear on Tour: BMW Championship\nWhat players are using this week at the BMW Championship at Cherry Hills Country Club in Cherry Hills Village, Colo.\nNike VR Pro Combo irons had been in Chappell's bag until last week's Deutsche Bank Championship, where he put a 4- through 9-iron set of Nike's new Vapor Pro irons (along with Vapor Pro Combo 3-iron) in play. Chappell claimed the new irons provided a higher ball flight with a tighter dispersion pattern.\nKirk first put Callaway's new Big Bertha V Series driver in play during the PGA Championship at Valhalla G.C. A few weeks later he was using it to win the Deutsche Bank Championship. The 9-degree driver's adjustable hosel was set at minus 1 degree loft with a neutral face angle directional setting. The lead tape Kirk added on the toe helps produce a slight fade bias.\nFourteen Golf has been making some steady inroads on tour this year with its wedges, including with MacKenzie, who put three of the company's RM-12 wedges in play at Wyndham Championship and has kept them in the bag since. The 50-degree pictured here has 12 degrees bounce with a raw finish head. MacKenzie had used True Temper Dynamic Gold shafts in his wedges, but switched to a shaft from Nippon that he felt offered better trajectory control.\nYou can't trust the stampings on Villegas' TaylorMade Tour Preferred wedges. In fact, the recent winner of the Wyndham Championship has the actual specs written on the back with a Sharpie. For example, Villegas' 60-degree wedge was bent to 63 degrees loft. Some lead tape on the back behind the impact area helps provide a mode solid feel as well as assist in achieving the proper trajectory.\nSummerhays has a one-of-a-kind Ping B60 putter. The putter, which features no alignment lines or stamping on the sole, was milled from 303 stainless steel with Ping's TR grooves milled into the face.
