I have changed the surface on the Big Shot several times in the last year.
4000 abralon pads don't seem to be quite enough if you have any carry down.
1000 grit gave me strong midlane and strong backend. 2000 grit seemed to work for me overall on THS. My wife likes hers with 2000 Abralon with light polish. This gives her good backend reaction on THS. Her Action Max is 2000 Abralon and no polish. This gives the Max a smooth strong backend. The best thing you can do for both of these balls if you have lost some reaction is the hot water bath.
The Action Max really soaks up the oil, more so than the Big Shot. I hope this gives you some idea of things you can do to change the surface and deep clean.
