I read up on this CushionTrack/PolyTrack stuff and from what I can tell there's not much difference between the two. It's Silica, rubber, other plastic and wax. If I were running Hollywood, I'd spend a few dollars and hire away someone from the Turfway track crew since that's the place where it's worked the best. If you get bored, here's the PolyTrack PPoint presentation to the California folks.
