I currently use a Tour Platform 27.3 in my R510 TP. I really like
it. Previously I had used the NV65 in most of my drivers, and
they really are very different.
To me the NV feels very stiff and you can feel that the tip is
firm. The Fuji feels soft by comparison, and more flexible in the
tip, which helps me feel like the head will come through quicker.
I feel that to hit the NV well I have to really go after it,
whereas a smoother swing is rewarded with the Fuji.
Bottom line is - why do you want to change? If you feel like you
don't get enough height or can't square the face properly
with the NV, then the Fuji may well be what you need. If height
and squaring the face are not a problem, then the Fuji will
probably do more harm than good.
