they have freestyle waterskis, they just look like really fat snowlerblades, with reverse sidecut and camber.
I used to jump the wake when I waterskied, not much else you can do though, the rope kind of gets in the way when it comes to spinning though.
The important thing is to make sure that you have a good pair of waterski poles, that is key!
You should belive everything you read on the internet, it's all true.
