I have a 915 D2 with a blue diamana 60g in S+ Flex and hit it well. I also have a 915 f 3 wood with a diamana blue 70g in S+ Flex and can do nothing but hook it. I rarely take it out of the bag now which is disappointing on distances where i need it. My natural shot i a draw but on days when i hit everything ok i still hook/snap hook the 3 wood. Should i try a different shaft? My swing speed is around 93 to 95mph.
