The NXT tour has less spin with the driver but it has less spin in the short game too.

Agree with Jan - The prov1 and x are best in class for pretty-much all categories and really reward you with a repeatable ball flight, spin and landing angle on well struck shots.  NXT tour is still a great ball and option for you, just a matter of playing one ball consistently so you are able to anticipate the performance on well executed shots.  Good luck!
