Recently went into a fitting not looking at just one specific club manufacturer but was interested in trying out the new 917 line and M1/M2. When hitting both in a 9.5 options I was getting between 9-10° of launch but spinning the ball around 3500-3600 rpm which was way to high. For reference we were using a 757 tour spec x in the TM heads and diamana white 70 x in the 917. We switched to the 10.5 heads to increase launch ( working on hitting up as opposed to down on the ball with driver) but still an issue with high spin rates now in the 3700-3800 area. The fitter then gave me the epic sub zero weight fwd setting in 10.5 with the rogue m-ax (stock shaft) 70 x and we saw spin number drop drastically to around 2600-2700 area. I like the looks sound and feel of the d3 head but what are some ways I can achieve the reduction in spin needed to optimize the driver? Thanks for any help and feedback.
