I got a chance to hit PING K15 Driver the new Callaway Diablo Razr 2012 driver that is adjustable, the exact same Cleveland CG15 Oil Quench Wedge setup at the Titleist 910 line. Actually, the weights are adjustable as well, so long Mizuno JPX 800 Driver to the i mix line, the new fully adjustable line is here. The driver is a forged composite and I believe Callaway X-24 Hot Irons it is 440cc. I will post pictures later. But overall, I liked the driver, it had a stock RIP NV shaft in it. Feeling was amazing, I found it to be shorter than the new Ping G20 line though, but just as accurate.
