The R9 every single time. Here's how it pairs up against a friend's G10 driver:
Driver: Me; L62 R9 driver (275 yards). Friend; L58 G10 driver (270 yards).
Balls: Me; Tour-SD balls (4/10 spin and 4/10 distance). Friend; Callaway Z balls (5/10 spin and 8/10 distance).
Spin: Me; Full backspin for tailwind and headwind - full topspin for headwind. Friend; Ditto.
So, with all that mentioned my friend should be hitting the same as me, right? Wrong! Instead, I beat him by 15 yards on every single drive.
GOTTA GET THE L62 R9...
