Hey I1,
I just tried my One at 500 grit and it rolls VERY well, I was getting some over/under from my One at 4000+polish so on a whim I charcoaled it down to 500 and it rolls real nice, early breakpoint, still strong on the back, more of a STRONG arc than a flip now. Haven't tried it on true soup, but it was at least 10 boards stronger than my Over Time at 2000 grit
