Focus on learning a BS 180 first. You don't have to do in the flats. If your sketched out on them, then slow the boat down, and learn to do them as an inside out. Once you get that down, then speed up. Just remember to think "regular wake jump". You don't need to rail into the wake to make the rotation, in fact if you go wake 2 wake, it will make landing the tanny 2 blind easier.
When you get the BS 180 down and move on, then do a nice and poppy tantrum, and give a good pull on the handle with you back hand to the back of your front hip. The actual rotation itself is pretty easy. Oh, and keep your eyes open too. Good luck.
