Have a question regarding surface changing with the schotchbrite pads, our oiler broke down 4 weeks ago and the first week we bowled on a broke down pattern and I actually did ok. The next week the lanes were oiled by hand, yes by hand and it was quit the night!!! The card in the machine was replaced 2 weeks ago and they haven't been able to get a shot comparable to what we had, we now have alot more oil then before and avg's have been going down since. I want to put some surface on a Radical Jackpot that I use and have a green and maroon schotchbrite pad, do you recommend starting with 1 grit and going to the next or just go with one grit?
