The key is to pretty much just stay in a ball.
For a cork 7, learn it this way. 180, to misty 540. Do a 180, land on the mat, then do a misty 5. Then do that a few times, then eliminate that bounce in between, so you just bounce up and do a 180 to misty 5 in one trick. IF you can't do a misty, well, just learn how. It's easy. just commit.
