Instead of using a tramp, I like using a rope swing, cause it's more like a real jump. Of course the one I use is absolutely HUGE(You can get 2-4 seconds of air depending on how high you start up.) I learned double backs and flatspin 7s this summer and I can't wait to try them on snow. I did them so often, that I could throw them whenever I wanted to without even thinking. Anyone else use a rope swing?
