yes I have wakeboarded before quite a bit. I dont have a boat so I couldnt go as much as my other buddies did alll the time. One of them does flips/360's/540's like its nothing now! I still have trouble doing simple spins. It really helps a lot if you know how to snowboard though. Since I do, I had no problems getting up but the tricks were a little harder!
And as mentioned before, just because its water, does not mean it doesnt hurt!! Oh and if you can get access to a boat with a tower, DO IT!! It will launch you so much higher!
