Moto whips help. Jumping steep jumps straight is scary as fuck, bringing the bike up into you and moving it around to match the tranny helps. Gotta stay loose and calm. No dead sailoring people! And steady progression is key, which means having your own trails that you built is what you want. You can make things progressivelg steeper as you progress, which limits the hurt. And have a smaller warmup set, nobody likes jumping cold. I would not reccomend going from dh style ski jumps straight into 10ft tall bmx trails with vert upramps.
