If you had Titleist reshaft it, the MSRP to reshaft the T Voodoo would be $110.00.  Spin/launch numbers seem a little high - what kind of numbers did you get off your 907 driver with the Prolite?

 I should have noted I am a +2 handicap.

With my current driver I get almost the exact same numbers with 8.5 loft and S flex, 12.5 launch and 4000 spin 275 carry. I saw across the board in all of the S flexes in the fitting cart while the launch and spin were different, the smash factor was always about the same unless I slowed down to 105 swing speed. I could certainly play the s and slow it down and hit every fairway, but I am only swinging about 85% at 120 my max swing speed I recorded in the 100 balls or so I tested with the fitting cart was 133 with three of the shaft, the voodoo, pro launch red, and pro force V2.

Ideally, my ball speed should be around 170 with 3300 spin. The Voodoo gave me the closest results, I like the heavier shaft.

I generally put a slide fade on the ball although I can hit it either way I wish. The fade generally adds about 350-400 rpm’s to the spin number.

Itseems to me that the s flex is just not stable enough to handle the speed, and based on the following table from the fitting section of Titleist’s web site

 the x flex should reduce the spin and thus increase the smash factor and overall carry. Maybe lower loft would get the ball contact higher on the face and increase launch slightly and lower the spin as well?

I'm glad you decided to go to Titleist O'side for a Tour Fit.  These guys are great and should be able to help you get your ball speed to match your clubhead speed.
