real cork threes are really really hard,everybody sems to think that if you just carve off a jump and bend at the waist its a cork 3, its not
you need a huge jump to do a good one, like atleast 60ft gap, then you have to do a slow ass rotation and just set the spin a little bit back off the jump, the bigger you go, the more corked you can get, grabbing saftey also helps to make it more corked
