I can do backflips on small-medium sized jumps. But when i do it all seems so rushed, so i want to try it on a bigger jump. Problem is i don't know how to lay it out. Any pointers?
I've never backflipped on skis so I don't know if this is helpful, but I've backflipped off of plenty of other stuff! Really try to scratch your back with your head. Your back is arched in a laid out backie. It's straight or tucked in a tight backflip. So really try and stretch your head around nice and smooth, and let your feet float out behind you rather than pulling them around quickly. Also as was said above, keeping your arms real noodly-like should help. Careful not to catch your tips!
Honestly it's as easy as it seems. if you've been hucking backflips on 15 foot jumps, try a laid out backy on a 25 footer with a long landing. Just pop, look back to spot the landing, keep your body laid out and let your legs hang back like you're Shane McConkey. If you're under rotating pull your tips forward at the last second. You'll know if you're going to underrotate since you've spotted your landing so early.
Try not to kick yourself in the back of the head and don't worry about catching your tips - it's really not as painful as you'd imagine. Just lay that puppy out like it looks in the movies and have fun with it. It's possibly the most fun trick out there.
If you just sling backflips off jumps without popping first, you'll have very little control over your rotation, and you might overrate on bigger jumps.
If you pop before you start your flip, you'll be more in control of the rotation, and can compensate--speed up, slow down-- as needed.
Don't huck it. Hanging your knees seems to help. IF you pop hard go up with it and pop toward being upside down instead of throwing the flip. Or float off the takeoff and hang your knees arch your back.
If you think you're going to over rotate sick out your arms chest and tongue to slow your rotation.
