Heres a funny old school clip I found on youtube. A little skurfing at the beginning, and then kneeboarding, but I found the commentary to be hilarious.
Dang I remember getting excited when I did a surface 360 back when I was 7 or something... About the same time this guy was doing all of those flips. WOW
I'm pretty sure I have an older wakeboard video that has a section with Randy Harris on the boat while Jonathan McDonald was kneeboarding...guy was going huge, doing flips way out to the flats and landing blind, etc. Kind of funny to watch Randy's reaction...appeared to be kind of into it, kind of.
Have you guys been in the boat with a kneeboarder who knew what he/she was doing? I laughed when my buddy told me he was bringing his kneeboard. The tricks he threw on it made my jaw drop. I had to bow in 'you are a bigger man than I' fashion because he had no regard for his knees, we went huge and every time he landed it made me cringe.
