I like using Abralon by hand, unlike sandpaper and scotchbrite the results look nice. I have a spinner, yet prefer the results I get using abralon by hand over that.
1000 grit abralon every 15-20 games and a quality cleaner after every use should keep the ball in good shape. If you notice any significant decrease in performance it may need a trip to the shop for a good resurface once in a blue moon.
