Replying to Sending off axis spins advice.

Okay so basically I’ve never done anything bigger than a straight 540 on a jump. And my mountain recently built a kicker that’s big enough to cork seven. It’s not huge, but it’s plenty big. I can do 5s and 7s on every axis on the trampoline so I have a pretty good idea of how I would rotate on a jump. I’m just afraid I’m gonna hurt myself trying it.(specifically I have cork 7 on my mind) but also wanna try rode 5s cork 3s and some bios. So any advice that will convince me that I’m fine would be great.
