This is pretty much the only torrent on the web concerning the sport. The video is in low resolution but still good enough (sorry, but that\'s the way I found it).rnrnrnFile Format: AVIrnrnEncoding: DivXrnrnDuration: 1:19rnrnIt\'s a pretty good instruction video showing many easy and difficult tricks. It\'s a little outdated but sports don\'t change much in such short periods of time.rnrnEnjoy.
