whirlys
 

i can land a whirlybird on the tramp 20 times out of 20. how much harder is it going to be behind the boat?

Depends on what your tantrums look like behind the boat. Really once you figure out the right approach and keeping your handle in, whirly's are super easy. Once you can learn a whirly, you learn why it isn't really a mobe

Other then the muscle memory once you are in the air. I would say it means nothing.

Yeah, its a whole nother beast on the water... its good you have the motion, but unless you do the tantrum start correctly the tramp-training won't help
