Contrary to the other replies I have installed several NV's and they are all different. they do benefit from spining and flo'ing. this goes for either the 65 or 75. No experience with the 55 or the NVS. Very few shafts can truly say they don't need spining. in my experience the top of the line Fujikuras (international series) come close as do a few others makes. But, as a rule, I always test for spine and flo. as to the cost benefit to making the change, I agree with the reply that said if you are hitting it well now why change? On the other hand if you are all over the map and never feel a consistant release toward the target then take the chance and do it.
