Okay, string update. 2.5 hours on one stick, 1.5 on the other. The NVy is about half shaved on the 2.5 hours stick. Pop is still there, crispness has fallen, spin definitely still there. I need to switch back to Wilson Supremes though, the SuperGrap is destroying my hands again. For some reason I thought I could start using them again, but nope, still too tacky. Wish I had some pacific grips though, those are my faves.
