hit a wake, get the ski vertical, grab the nose then do a handstand and land back in the water on your back in front of the ski?
I saw a vid of someone doing this HUUGE off too wake boats but cant find the vid. post it if you can find it.
If you only touch the ski with your hands as you go up/over, it's a Sprung Monkey/Canon Jump.
Here's some quick definitions.
Ball Buster=jump ski vertical getting whole ski out of the water, jump up and grab nose, ride ski in while vertical, ride out on hood.
Monkey Jump=Hop ski and bring nose up, jump up and grab nose, hit throttle with foot, flip over ski.
50/50=Luke's First Vid. Jump ski vertical getting whole ski out of the water, jump up and grab nose, ride ski in while vertical, hit throttle with foot, flip over ski. (Half Ball Buster, Half Monkey Jump)
Sprung Monkey/Canon Jump=Luke's Second Vid and in both of Bartolameolli's vids. Hop ski and bring nose up, jump/flip over ski in one motion only touching ski/nose of ski with your hands.
