Mizuno 630 Driver - Avicore 79 or Fubuki Shaft?

[PPE]

I already own the Fastrack 630 and want to get this for my carry set.

Its only £79.99, or £72 from onlinegolf with credit and £84.99 from clubhousegolf (inc postage).

I already have the fubuki shaft and its briliant and I dont alter the weights really, but I do hit the ball fairly high and swing at 106mph. I am looking for the 9.5deg. Which is the better shaft for me?

Anybody got this in the Avicore 79 shaft?

Had one with Axivcore 79 (10.5 loft) and found that it was still slightly whippy. Current MP630 has the Mitsubishi Fubuki and it is awesome. Don't feel any whip in it at all.
So for me (swing at 102Mph) the Fubuki every time.
