heres what worked for me:
1)hard toe edge in,
2)let off your edge and go flat at the bottom of the trough ,the wake will trip you without you even having to do anything.
3) once in the air, bring your knees up/in will rotate you faster.
4)(pretend or try) to grab, that will get you to let go halfway through your rotation.
I know its a lot to think about, "}The Book" helped me with all of this. before,I could land it but was always butt-checking becuase I was under-rotating.
