no way... i think cork 3's are way easier if your doing them right...
No one get all pissy about this..but the reson why you think cork 7's are probably easier is because your chucking your body/arms and not actually spinning with the core of your body... on cork 7's you have to commit alot more than on a cork 3, with a cork 3 you can start off just a bit off axis and go to the extreme of getting bascially inverted...
....sorry i totally was gonna post two different examples of corks that i do... but i think i deleted them from here...anyways theres one at like 35 seconds into this...
