MY BAG: Bill Haas

"I put the 915 D2 driver in play [late last year], and there was no adjustment really. It's the same shaft too. Being able to put your old shaft into your new head makes it pretty easy to change."

TECH TALK

Weight Shift

TaylorMade R15 driver

A pair of 12½-gram sliding weights in the sole track provides five grams more movable mass than with the single 20-gram weight in last year's SLDR driver. Positioning the weights in the heel and toe increases the club's forgiveness, moving one of the weights to the toe and the other one to the center adds fade bias and so on. An upgraded adjustable hosel enables the loft to be increased or decreased by as much as 2°. The 40-gram sole track is more flexible and closer to the leading edge than in the SLDR 460, which generates higher-launching, lower-spinning shots that have a marginally higher peak height. Justin Rose, Jason Day, Sean O'Hair, Justin Leonard and John Senden are among the Tour players using the R15. $430; $500 with TP shaft.
