Backside Back Roll to Revert
and Half-Cab Roll
The half-cab roll is a switchstance backside back roll to revert. So both tricks use the same exact technique - one just happens to be switch. Before you head
off tryi your roll to revert you obviously must have your backside roll wired. Then get the hang of doing simple backside wake jumps to revert, letting go of the handle with your front hand at the peak of the jump, then concentrating on pushing your trailing hand to (or behind) your trailing hip so you land revert. Get really used to the feeling of landing a big jump switch.
When you are ready to throw the actual roll to revert, go through the normal roll procedure. Halfway through the roll, start to bring the handle towards what was your trailing hip. About three-fourths through the move, let go with your normal front hand and push the handle back behind your trailing hip,
Some people learn this as their first roll simply because it is easy to practice on the trampoline, diving board, etc. But most people really have a hard time with this trick because their frontside edging isn't as strong as it needs to be. Before attempting this trick, make sure you can sky your frontside jumps as big, or almost as big, as your backside.
You need to carry an extremely strong edge into the wake. As P.J. points out, to get a true frontside edge you have your hips and toes pointing away from the boat. A lot of people can't get enough angle to the wake on this cut. Try to get the board pointing toward the wake, not the boat as you cut. "Plus," Marks stresses, "your hips should be straight to get the cut - bend at the knees. A lot of people initiate this trick bent over, but you should hit the wake straight and upright." Most of the problems in this move actually come from the cut, so if you've got that down you shouldn't be too far from the frontside back roll.
Dave Briscoe from Ski Away Ski School in Winter Haven, Florida, says there are two ways to do this move. If you can do a back flip on a tramp you should do the move with the same rotation as a tantrum.
So take a progressive cut on your toeside edge with dominant weight on your front foot. He stresses not to cut too early in the move. Just drift to the spray mark (about 7 feet outside the wake) and build your edge from there. That way you can have maximum edge at the top of the wake. On the top of the wake, go from your toes to your heels, throw your head straight back off the top of the wake as you would doing a flip on a tramp, and let go with your rear hand. As you spot your landing think about bringing your knees under you, not your board.
If you aren't comfortable doing a flip on a trampoline or a tantrum, then at the top of the wake instead of switching your weight from toeside to heelside, throw your head away from the way the boat is going and turn your hips to where you are looking. For this style of frontside roll, Briscoe says it's best to keep two hands on the handle; however, this tends to cause you to land revert. Another common problem here is having too much weight on back foot. If you leave the wake on your back foot, you land on your back foot, which makes it hard to hang on.
