if your getting flip turns its not that much further until your can helix.
Flip-Turn you stay on the same blade and slam the strern back into the water to pull you back in to a front surf.
Helix you stay tucked on the front of your boat and let your momentum carry your through the final part of the rotation is rolling up on your opposite blade.
Say your initiating left
1 - go down the wave and initiate a bounce and start your boat spinning left.
2 - using your left blade do a back sweep, and pull your right knee up & towards your head (flipping you upside down)
3- as the sweep runs out of power stay tucked forward & watch the boat rotate above your head.
4- reach around and do a sweep roll with your right blade. (This brings your upright & gives you the final bit of rotation to end up back in a front surf).
Check out Ken Whiting's DVD's for a really good explanation. EJ's Advanced playboating also has an explanation but not as clear. (Although I havn't seen the new version of EJ'S playboating.
Really fun when you stick them, I found medium sized 2-3 ft waves nice when learning (still learning really) enough power & speed, but not too intimidating.
Good luck & Happy boating
