I had a fitting this weekend with a Titleist rep. The best combo for me was the D3 with the Px 7C3 shaft or the HD6. Both had very similar numbers. I had the 8.5 set to 9.25. What could I expect if I went to either shaft at 9.5 degrees. Not as concerned about spin as I am with launch angle. Launch angle at 9.25 was right at 15 degrees.
