Sorry to hear about Horsham. I wish I could share, we could use more carpet racers around here. I'm moving to a place in the spring where the carpet track just closed, and the racers have managed to get together and form a club, buy carpet, and hold races at the fairgrounds. Hopefully it works out for them, I'd really miss the rug.
I'm going back to foam (and NiMH, bleh) next week, and was thinking about using Schreff's Horsham setup from a couple of months ago as a starting point. We don't have high traction at the moment, though I think we're going to start spraying Paragon again.
