Chris,
The swing weight of a 910 is around D2. I don't think if you match the swing weight of your 975 you will get the same performance. The graffaloy and Ahina have different playing characteristics. Why not get the graffaloy put in the 910?
The weight kit helps ensure either Tour preferred swingweight, D-4 or whichever swingweight is preferred. Virtually no performance changes, only confidence and feel.

I filled out the same survey a long time ago, but haven't received any Pro V's.....Should I have?
This is much more like it, 60-70*, greens hold the ball even though they are a bit tough to putt.
Bumps weren't too bad(except hole 9 managed a 3 putt, had to be the greens fault).
Wind was whipping around wildly, 1 way then another, different directions…
I recently purchased a new 910 D3 driver in 10.5 degree with Ahina stiff shaft.
I was fitted at a local dealer with a 9.5 degree 910 D3 with Kai'li stiff shaft but it produced a slightly too high launch and spin rate.
We tried various other shaft…
