Getting as much of myself and the board over the other side of the wave is what works for me.
Up to chest/shoulder high. Its worth paddling/popping over even if you fall cos 9/10 you will be up over it by the time you fall.... and sometimes you make it - no better feeling!

You get more of a kick with full nose boards so get in the surf stance and be ready for the slap.
Shoulder high and up. Flicking the board over the whitewater works a treat and you then dive under - no drag and it is waiting for you on the other side.
Big and sucky - dive deep and get ready to have your leg pulled off!

If you lying down a Nipper pop-over works well. It is like an ollie - bury the tail and flick up and over with the rebound.
Happy days
