Kenny Perry's Longer Driver

Just before the Masters, Kenny Perry switched to a TaylorMade R9 driver. He said it was the straightest driver he'd ever hit and nearly won the tournament using it.
At Colonial a few weeks ago, he switched to the TaylorMade R9 460, which features a larger head and a greater moment of inertia.
According to Wade Liles, a Tour rep for TaylorMade, because the R9 460 resists twisting on impact so well, thanks to that high MOI, Perry was able to go from a 45-inch driver to a 45 ½-inch model without losing accuracy.
That may not sound like a great deal, but a longer driver should help the 48-year-old Perry hit the ball farther. With rain expected here Thursday, Friday and Saturday, those few extra yards off the tee could be precious.
