What effect does increasing or decreasing the weight in a hybrid/fairway wood/driver have? I have a problem with hooking a 19 deg 910 H when I'm not looking. I have adjusted the loft/lie settings, with not a great degree of success and wonder if adjusting the weight would help (I have the standard 7 gm weight in there currently). I have a 90-100 mph swing ( not fast but good rhythm) and a Diamana Kai'li 80 stock shaft, which feels a little inflexible. I have a 910D3 and 910 Fd with stock shafts, which I don't have the same issue with. Any suggestions on weights or shafts?
