I learned this trick at wakeboard camp three weeks ago:
1. You need a good wide heelside cut to build quite a bit of speed into the wake. Faster is better for this trick as long as you're in control. Be 100% comitted to throwing the trick. You can't be apprehensive.
2. As you get to the base of the wake, flatten out your board and start to turn as if you are going to cut into the wake and surf off the wake back out into the flats where you came from.
3. When your board and your shoulders are heading in the same direction as the boat (parallel to the wake), stomp down on your front foot, let go with your back hand off the handle, and open up your head to the sky (look up), while you straighten out your legs. Don't throw your head back, but look up to the sky.
4. Doing #3 correctly will 'trip' you and pop you up at the same time.
5. Throw your legs over your head. If you can do it a bit tucked instead of layed out, you will rotate faster. Over rotating is ok as you're learning the trick. Under rotating is bad and will crush your ankles. Trust me my ankle got crushed.
6. Try to spot the water when you're coming around. If you're rotating too slow, and can't tuck it in anymore, try giving the rope and extra tug while you're flipping.
I know it's alot to try to remember when everything is flying by in a blur.
