I am torn between what shaft flex I should be playing. I went through a Bridgestone ball fitting on 6/15/2011 and had the following results.
Swing Speed 98.0 MPH
Ball Speed 133.8
Launch Angle 1.2
Back Spin 3,197 RPM
These were with the use of a Callaway 9.0 degree driver with a stiff shaft.
Since then I have purchased a 10.5 degree Cobra AMP with a stiff shaft. I hit this club with a slight draw. My misses seem to be a pull hook.
I will tun 66 at the end...
