The tantrum is one of the first and easiest inverts to learn. The rotation is easy because you can spot the water early, like doing a back flip on a trampoline. The only part that I find hard for people to master is the edge change.The whole key to this trick, and for that matter, any trick, is the cut. Unlike a wake jump, a spin or most other inverts, this trick is not done with a progressive cut. You actually have to cut hard out in the flats and then back off two-thirds of the way in, let go with your back hand, stand tall and ride up the wake. Keep the rope tight so that you will rotate around it. This combination of speed and edge change is the mechanism that sends you up and over.
