I'm very interested in purchasing a 910 D2. I have hit one with two different shafts; the RIP 60 and the Kahli 65. With the RIP my launch angle was between 10 and 12 degrees, 132 ball speed, angle was basically from -1 to +1 at impact. Spin was 1800-2200. The Kahli launch was between 14 and 16 with spin between 3400-3700 (same attack angle), ball speed 132. The RIP seems too low and the Kahli it appears to have to much spin. Any suggestions/advice would be appreciated. Dale Barnes
