I/ve only used mine for 18 games. I am a low rev'er, used #7 and love the ball. I did clean it with Clean N Dull after 6 games. I did notice a slower break to the pocket after the 6th game, so I cleaned it and it was like a NIB ball. The color, or lack of, came back and IMO, that's what one wil have to do to keep this ball in OOB condition.
Mine also had a fight with the belt, a few scuffs, no scratches, and the C N D took them off with no problems.
I drilled my wife's N/M, and Tues night she'll use it for the first time. I already know what to do to keep her's in good shape, but I'll let you know what she thinks of it, BTW, she is a slower speed, med/higher hand, low tracker, so I used #2 for her layout.
Maybe this has helped, maybe not.
