I currently play a 910 D3 withe an Ilima (61 g) "S" flex shaft. Loft is adjusted to 11.25* and backweight is adjusted to 5g. At times driver feels light and there is a tendency to hit from "the top". Most of the time, however, I hit it fairly solidly and very straight, but don't seem to get the distance I feel I should. Wondering abut your thoughts on whether I should either add weight, reduce loft or make some other adjustment to gain some distance. The distance would be nice but I'm reluctant to give up the consistency and accuracy. 3 handicap, moderate length hitter.
If the club feels light, then certainly changing that bezel weight to a heavier option will help. This weight only has an effect on swing weight and won't effect your ball flight. There is a chance you may have too much spin with that shaft or loft, which could cause the reduction in carry distance. Either lower the setting on the driver or try a different, lower spinning shaft. This is something that I would recommend seeing a Club Fitter for, who will be able to analyze your ball flight and put you on a launch monitor.
