Let me start by saying that my swing was not good when I went for my fitting! Lots of low slices with way too much sidespin. I tried the QI10 Max, AI Smoke Max, Darkspeed Max, as well as the Dark Ops, and quite a few different shaft combinations with all of them. Way too much spin for me and not the improvement I had hoped to see in carry and yardage. Finally tried the Srixon ZX5 MK2 with a Tensei White S 65. Even with my poor swing the spin was much lower and the carry +10 yards over everything else I hit, and 17 yards over my current gamer. So it's in the bag for now. 2hrs on the simulator and had my swing in much better shape and was seeing even better results. Played yesterday and the horrible cut was back, I had a couple of nice drives with it but nothing was working, but I can't attribute that to the driver. Back to the range after work, I do feel that once I get back to my normal swing I am going to be happy with it but we will see.
