On the red one with all the twists and turns, if you get a good start and keep a good line, like bobsledders or the luge, you get great speed through the turns.Start turning your body into the turn before you actually start the turn, you will be amazed at the speed you can get. When you land you are dizzy, especially after a couple Presidentes. And dont wear a shirt. Now I wish we had it higher and longer!
