I'm looking at moving from my Rip 80X in my 910D3 to something in the 70 gram range with more feel... I'm considering the Whiteboard for its butt soft profile and consistent results and the new DI from Graphite Design. The feedback I've received is the DI will only launch a degree higher and for some people actually lower...I've also heard it should spin less than the white and have a better angle of descent.... This confuses me as the fitting chart has it much higher launch and spin. What is the consensus on this shaft from Team Titleist as I've heard from people playing or who have hit both who say the DI is a better performer...
