Those are unreal for shinbang.
However the best solution for shinbang is to stop landing backseat! THats what causes it... landing sitting down a little. What tricks give you shinbang? I'll bet you need to work on your takeoff making sure you've got a strong pop and you're on balance.
Landing backseat is death for shins... something about the muscles ripping away from the bone or some shit like that.
If you land backseat, just fall. Don't fight it. Only the perfect landing should be landed!
