For the life of me, I have not seen anyone, anywhere, scoring great with a Nano anything......to the point where I'd say, "I'd like to see a certain ball, with a Nano cover on it."
What is it that folks like about the Nanos? I have bowled with folks in league and tournaments throwing Nano covered pieces and they don't react anymore spectacularly or special than any other ball being used! at least from my observations.
