Use an older pair you've already torn out the edges on rails for snow, that you don't plan on using again on snow,
Chances are you will snap them eventually depending on how many jumps you do in a day, and which kicker your hitting,
You have to wax the bottoms so you don't get kneedy burn, which will slow you down going off the ramps, also you won't want to use the bindings again after they've been in and out of the pool a couple hundred times, the spings will be shot.
I used to have to reninforce skis with a fiberglass topsheet,
use old skis you don't plan on using again on snow...
