I would like some insight as to which shaft ; I should maybe consider using in my 915 D2 - 10.5 deg loft driver. My SS is mid 80 to low 90 mph and I currently have the regular Mitsubishi Diamana S+60 gram shaft at the moment and would like a heavier shaft option . The reason that I ask is that my 3 wood and Hybrids are all Titleist and all of them are 70 gram regular shafts that I hit fairly well slight draw at most times; but with the driver ; it is a pull hook- hook at most times. There will be having a Titleist fitting nearby in 2 weeks which I'll attend but any help with this would be greatly appreciated.

Thanks Marc J
