For what it's worth, I've been using a Nano since they first came out. I loved the oob finish until it was time for it's first tune up. Seems for me, the ball now works really well for about 6-9 games after touching up the coverstock, if I've been playing in heavy oil. What I've read about this ball being high maintenance is absolutely true for me. Even though they say it has a 4000 abralon finish, I've read somewhere where it had been checked and was actually under 1000. Seems they use 500 grit abralon on the ball and briefly and lightly hit it with 4000 just to round the peaks a bit. I just took mine off the spinner and left it at 500, hoping it does better in heavy oil. I agree with the above post. Seems my nano also labors in heavy oil. Contradictory to what's supposed to happen, it seems I get better back end reaction using my nano on med to med/light shots when it appears it's burning up it's energy through the front and middle.... Something is definitely different about this ball, but I love it, most of the time!
I'd love to hear what others have tried for surface with a nano and their results...I've noticed not many of the pros are currently throwing them since it's big debut.
