So I had a fitting last week and tried all the new drivers against my old Cobra Bio Cell, I was amazed at the difference in my driver to the new ones in ball speed and dispersion. In the end the Epic Flash SZ was the winner , it cam down to the Flash SZ and the Cobra F9, I took them out to the range after the fitting to verify in real life and outside the SZ was by far better on dispersion, dead straight on good hits, the thing that really got me is my misses still hit the fairway most of the time. Of all the shafts I tried the Evenflow Black 65 X Flex gave me the best results, I am totally impressed with this driver. I am 51 years old so I am going to take advantage of this distance gain now before my SS starts to go down hill. Purple is my cobra bio cell
