flat spins are so fun to do but so hard to get really flat. And there so hard to do on the tramp because your going up and down not forward. Once you have your back flips on the hill all killer like, start working them to the side a little by little keeping your head up. then one day you will find they want to start going to 5 on there own and its up to you to fight it and keep it at 3 or let it flow and go to 5. When this happens make up your mind b4 you hit the ground. so you dont end up 90
