I think more loft will promote a better release motion. I find that a player of your caliber can benefit by increasing loft and increasing weight of the shaft. Loft at impact produces launch angle and shaft flex and weight produces spin. Try a 10.5 with a heavier shaft just to see what happens.
I tried out some drivers on the launch monitor today, specifically a heavier shaft than my 65 gram. The heaviest I could find in the store was a stiff, 77 gram UST Proforce V2, but the head only had 9 degrees of loft. As expected my launch angle wasn't very good - 9.7 degrees, but my spin went down under 4000 rpm...3800 - still a little high. I have a couple questions:
Is it better to go heavier or stiffer on the shaft to get the spin down? What are the dangers of going heavier? I've also hit a friend's V2 x-stiff (same head), and I liked the way both the stiff and x felt.
Jeff, I remember you were hitting an 11 or 11.5 degree driver at the swamp last January. Are you still using that driver? I know 10.5 is a pretty standard loft for off-the-shelf drivers; is there a "favorite" or suggested loft that you find works well and encourages a good release with many golfers whom you fit?
