Also, someone suggested that I try to go more up, but when I do, I get lots of air with under-rotation.

Can anybody tell me what I'm doing wrong? This has been driving me nuts, I've wanted this move for so long...

To me, it just looks like a momentum thing. The first video looks like you got a lot more power/momentum using your arms and such. Just try using your whole body to get more power.
