I'm kinda backwards from everyone else lol. I started riding snow to cure my wake jones. It is a brutal sport, had my share of hard diggers. No matter what invest in top level bindings, nice and snug, most knee injuries are caused from a 1 in 1 out crash (where 1 foot comes out the other doesn't)
The main difference between wake and snow is how you use the edges, wieght transfer is about the same, but on a WB you lay it on edge to accelerate into the wake, and flatten to slow down, completly the opposite of a snowboard. Then there is the rope to deal with, you have to keep it in your mind that you are on a pendulem from your tow point, and rope control is key. Whoever said keep it low on the hip was exactly right, feels wierd at first, but this is how you center all your movments, and initiate spins, both surface and air.
