I have 915D3 10.5 blue diamana 60 stiff. The issue is spin rate on trackman. I'm trying to lower spin rate. What settings should I try if I'm fighting a fade. If you have suggestions for setting for 915F diamana blue 70, and 915h diamana blue 70. Swing speed on trackman average out of 6 shots 100mph with driver. Just confused and wonder if Surfit will help or if it's just better to leave standard in A1. I know Surfit is just for fine tuning. Any help would be appreciated. Thanks.
