I got a 9.5 910D2 from my friend the other day and I like all but one thing. My drives fly way too high. I set the SFT at C1 but it still goes too high and I'm losing distance. The current shaft is a Graphite Design YS6+ 65, Stiff flex. I'm looking for something 65 to 73 grams, low torque, X stiff. I'm thinking the Fujikura Rombax 6X07, Diamana White 73, Project X 7C3, or Proforce V2 66. Any suggestions would be great!
