yea the cat twist mid jump screwed you up.
the generic advice for inverts:
-start in a t-pose
-take off with both inside edges digging into the snow. keep you feet wide
-dont forget to pop/hop up. dont set backwards on the lip, this will put you backseat on the landing
-let yourself come up before tucking
-hold the tuck past the mid point of the jump
-after 5 release the tuck and watch for the landing
you already have the hardest part of a cork 7 down, the commitment.
you dont have to get fully corked on your first attempts.
start with a straight 7 + safety and work your way back on the set. cork or not cork is | or / on the set.
