I have been using prov1x for some time. I recently used a prov 1 and i was hitting my drives 15 to 20 yards further...does anyone understand how that could be as the x is said to be longer?????
I play both, The X for wet or damp greens and the V1 for normal green conditions.
Truth be told I am only getting about 3 or 4 yard's more with the X.
I think it's probably related more to your swing than to the ball you are using,
