I'm in the same spot as you. I'm sure you've already done a 360 and stuff just like me. I think Im going to try to commit to a backflip this season and then maybe a rodeo or cork next.
A backflip is easiest to practice off snow. (Just get them worked out on the tramp). I know they transfer to snow pretty easy too. I haven't brought myself to do a rodeo on snow yet but backflips came pretty natural. Especially since they only involve rotating on one axis. So it's ultimately a matter of personal preference but I would go for the backie first!
