so i guess you are doing what some posers here are calling throwing corks. its so hilarious, everytime, when they just flow out of the lip so theyre head/feet axis is at about 20°, and they land kinda backseat, its a cork 5 or a cork 3. they dont get it that cork 3s and 5s are different tricks, not just leaning backwards at the lip....
but really, try to pop off the lip or try to get a grab in it, safeties are keeping it straight, if you ask me
