i have a friend who does all this shit it's fucking insane, but he does it competitively, not on a backyard tramp. i've never seen anyone do shit like this on a backyard tramp before, that's crazy.
Notice that green shirt lands in almost exactly the same spot on the tramp that he takes off from every time. White shirt drifts; that's why he was bailing early on a lot of his tricks. Biggest thing is making sure when you flip or rotate, that you are landing in almost the same spot. Makes a huge difference; gives you more confidence to try bigger stuff.
