In my opinion, the only reason to own a ball spinner is to polish a ball, and those things just don't create enough RPMs to shine a ball. They come out looking duller. Just my experience and opinion.
More than likely true. I've been cleaning after every practice and league. I also just started to touch the ball up with an Abralon pad, by hand. Is there a real advantage to Polishing the ball? I tried that a few times last year by hand, and realized it was a losing battle.
Right now after I use the pad, I clean and
wipe off, that's about it.
