The AI and VZ, the two Rough Buff balls so far, have 220-grit bases before the RB is applied. Both are pearls. The Shock and Awe, too, I believe. RB is a compound polish, the ones I've seen are around 1000-grit, maybe 1500-grit. Almost shiny, but not quite. I don't know about High Gloss. I believe HG is a grit-less polish, so it shouldn't change the surface from whatever's underneath, typically 400-grit for Brunswick.
