If you're really a dick, then yeah, you'll knock the lip, I mean, I don't get how ppl manage to knock the lip :p
Okay, but just incase, for not hitting the lip, think to pop, litteraly wait until your skis are half way oof the kicker then pop pushing your head as if you ganna break your neck, bring you knees (knees actually come up quite automatically) spot the landing, open and smile :)
