I have a dilemma in front of me. I have a chance to buy a 910d2 or 910d3 driver. They are both demos for an awesome price (half off). They both have diamana stiff flex shafts at 9.5 degree. I am about a twelve handicap with a swing seen of about 95mph. I can not hit either one of them as there are at a golf shop where my buddy lives. Which one would be a better buy? Thanks for the help gents.
