Well bought the new 915F 13.5 degree with the Diamana white shaft today. I thought that it was time to upgrade from my 910 3 wood although I still could hit it well. Sure hope it's as good as they say. Guess I will find out in 7 - 10 days. I found that while hitting the 15 degree 3 wood option that my ball flight was way to high for my liking and that I was losing some distance they did not have the 13.5 to test there but the fitter said that it will help lower the ball flight for me with the shaft combination. I was wondering if there was some insight on this out there that would help me. As my 910 had a lower flight than the 915f. Thanks Todd
