Titleist 910D3 SureFit question

Was hitting my driver (9.5* D3 w/ Proforce V2 65g shaft ) on a launch monitor yesterday.  Launch angle looked good at 13*, but my spin was around 3500 rpm.  What setting could bring the spin down to about 2800 rpm? Or do I need a different shaft, such as Project X (which I have and love on my 910f)?

Thanks!

Can I use my 3wood shaft on my driver? Are the hosels the same?
