you need to wrap more rather than drop your shoulder straight back. start a wind-up type motion and throw like that instead. you almost wanna cork the last 3 of the rotation instead of the first 3 ya know?<br>
yeah i had this problem too. the problem is you drop your shoulder back while you're still on the lip. just wrap a bit more and don't drop your shoulder until you're well in the air and your cork should get way better. on the other hand. after having this problem I ended up getting two tricks from it: cork 7 and underflip 5
