I posted this on another "backroll" thread.
The Backroll is a relatively easy trick to do, as long as you've got your progressive cut down. Without the progressive cut, you will get worked! This is what works for me and I have taught this trick to a few people this same exact way. It may not work for everyone.
1. Cut out about 10ft. from the wake. (Yes, 10ft. The key isn't a hard cut)
2. Start to drift in towards the wake slowly.
3. Once facing the wake, start to lean back on the rope to cut harder. Remember to keep your shoulders up, and not back.
4. Make sure your hardest cut is at the wake. (As stated above, the key isn't a hard cut...the key is a progressive cut, w/o flattening out)
5. Stand tall and keep the handle at your lead hip at the top of the wake.
6. As your coming off the wake, make your board go straight up and at the same time, look UP and OVER your lead shoulder. DON'T JUST LOOK OVER YOUR LEAD SHOULDER AS THIS WILL LEAD TO AN OUT OF CONTROL OFF-AXIS SPIN.
7. Keep the handle close to your hip with BOTH hands.
8. Keep your eyes open and spot your landing.
9. Absorb the landing by bending your knees and continue cutting away from the boat.
Like I said, it's a relatively easy trick, as long as you've got your progressive cut down and you commit to trying it. Don't half-ass it. Give it your all. If you apply the tips correctly, the rope, board and boat does all the work...you're just along for the ride.
