It's hard to explain it on a forum. I'm sure if I were with you and you can do tantrum and scarecrow and ts 540 on the trampo and could help you doing whirly, crowmobe and off-axis in less than an our. I teached my friends who don't wakeboard and could only do frontflip and backflip on the tramp how to do mobydick, crowmobe and off-axis.
You should consider learning a mobydick on the tramp before a whirly if you don't even got this trick.
I've a little video that I've made a years and a half ago all tricks in a row so some tricks or really ugly such as the whirlys lol but you'll get and idea of how to throw the tricks if you check it in slow-motion
