...no actually cork 7 is the easiest cork and cork 3 is the hardest.. when i cork i like to throw a bit forward (i know everyones thinking misty/bio but bare with me) and then i let my body rotate flat until my head is facing the jump...a lot of people actually do this and it is just like corking the other way.
