Anybody paddled both in the surf?

I've got a 12' 6" fiberglass WaveWitch as in
http://www.huntjohnsendesigns.com/index.htm
and have been enjoying it a *lot* since early spring - both on flat water and in
the surf.

Only problem I have with it in the ocean surf is not becoming a wave hog because
it's so much easier to catch waves with it compared to the people on poly
sit-on-tops.

But I only recently became aware of wave skis as in
http://www.youtube.com/watch?v=PMrwTIdue0M

Can anybody comment on the differences/similarities in function/technique?

Surfboard-analogy-wise, I'm thinking longboard vs tandem board.

I'm kind of all alone out here - there's nobody to watch/emulate.

Should I be trying to emulate the moves in the YouTube video...or is it futile?
