No it wont cause you to flip. I wont try to annoy you and tell you to neck up, but have you tried tuck jumps off normal flat ground (no snowboard, just bare feet or shoes) to see if you'll flip? Makes you wonder why someone posted that. Anyway, flips require you to throw or adjust weight from your upper body i.e. dropping a shoulder, tossing your head forward/backwards etc. Tucking your knees may help. The compactness certainly would. But in and of itself, no. Or we'd all be doing mad spins everytime we grab Indy.
