This summer i took of with kneebaording and i was getting so much air of the back of my freinds x-10 that i could have done some serious tricks. how can i do a barrel roll? and how can i do flips?
All the same principals of wakeboarding are used in all watersports that require some sort of lift. Whether it is wakeboarding, kneeboarding or ski jumping, you have to do the same thing: edge progressively and load the line. By the way, i'm sure if you looked hard enough you could find some fantastic videos from the 80s and early 90s that have instructionals. I know I actually watched one last summer where they were doing all kinds of flips on them.
I used to knee board until I learned how to ride a wakeboard. I could do backflip after backflip, but could never get any spins. Now it is for the girls on my boat that cant wakeboard.
