Yep...I spent a lot of time over the last year chasing that magical 16-17 launch and 2200 spin. Best I could get to on a launch monitor was 14 launch. All I got was a high drive that came down soft and didn't roll. Frustrating.
On a whim, I bought a Cobra F9 with a low launch HZRDUS shaft just because I wanted to check out the F9 head. Left it on the 9 degree setting, and played Monday. I had several drives that just rolled and rolled and ended up a good 20-30 yards past what I expected. So I took my gamer F8, tuned loft down from 11 to 9.5, and it was going 20 yards further. Here in SoCal, firm and fast fairways don't need that 16-17 launch.
