@bsmith. I'm no expert, but FWIW. A friend of mine was a very good three event skier, and a pro jumper for a while. He put his kids on Hyperlite Motive wakeboards as a lead in to trick skis. The Motives start at a size 118 kids version and went up to at least a 140. I see them used on facebook market, craigslist, etc. In the case of my my friend, he mounted the boards with Liquid Force Bindings that had a swivel base. Just loosen a couple of screws and easy to swivel the bindings forward. He removed the fins from the wakeboard. Every so often he would swivel the bindings a couple of notches forward, getting them closer to trick ski position. When the bindings were swiveled as close to trick ski configuration as possible, and the kids were comfortable, he moved them to a trick ski. They did not lose a single trick when making that transition. I'm a lousy wakeboarder, and even worse on a trick ski, but my experience is that on a wakeboard I can usually do S, B, F, WB, WF, and the reverse of each. That's worth about 640 pts. Sometimes I can do an O and reverse, that would be another 180 pts. On a trick ski, I'm still struggling with starts and a side slide :) which is the point of the original poster - Trick skiing is hard.
