Why not take the realism even farther and just code the character to afterbang when you land a trick smoothly anyway. I mean you shouldn't be trying to afterbang your tricks anyway.
i usually try not to be this guy but skiing is literally 10 years behind with the whole afterbang thing. it was a joke in snowboarding by 2002, as evidenced by the robot food film called afterbang (posted above by someone actually (best snowsport movie ever by the way))
Afterbang would be pretty cool. It'd be way sicker if it wasn't a button but just happened naturally if you landed clean. Not sure how much work that would be though. I shall have to check it out.
