I can tell you from first hand knowledge to avoid 303 on the tramp. Althogh it looks GREAT! its slick as snot! No one got hurt but it was 'bambi on ice' for a couple of go rounds. we laughed till our guts wanted to bust. it was so funny watching us slide around. If only i could have grabbed the ring and hooked up as i shot across the tramp. we could have had some 3 sec tacks!!! i'm laughing again thinking about that... you could bring some along to your next race and use it on your buddies tramp
