AP2 with rifle shaft

I am playing 710 AP2's with Rifle 6.5 Shaft, my swing speed has slowed to around 90, is this still a good shaft or should I change these out

Rick, 

If that is your club head speed with a driver, then those shafts may start to feel slightly stiffer then needed.  This is certainly only judged by your own feel and consistency, but if you do feel they are firmer then they should be, consider the 6.0 or even the 5.5.
