I own a Cobra F9 driver at the moment.
I play it at 8.5* with a Hzrdus Yellow 6.0 shaft.
Before that i played a Callaway Epic SZ, and i must say the Epic was a longer and better driver than the F9.
Not going back to Epic SZ (newer is better), so wondered what experience people have with the M5 (better still if you have hit the F9)?
Is it a bomber?
My spin number with the F9 is way to high - about 3500 rpm.
