This trick is simple because it is just combining two simple tricks. In order to do this trick you must first master the 720 corkscrew and also the backflip. But once you have those two things mastered it is all about how you combine them and what your comfortable with. Everyone is comfortable with doing it a certain way so it is your job to go out and try to do it. But keep in mind that while doing this trick you want to cut out as much possible time in between the two tricks(in other words you don't want to pause in between the two).
