When you start your turn outside the wake you should get your body in position as you will go off the wake except your knees will be bent just a bit more.
Don't lean too far back because you will go screaming in and will have to let off before you hit the wake to be in a good jumping position. Just start your cut easy pick your line to the wake and stay on that line keeping your body in one position.
As the boat moves forward and you stay on your line, you will build tension (energy) in the rope. Stay steady. Don't lean back too much and don't let off when you get to the rampy part of the wake.
When the front of your board hits the curl, stand tall, keep the handle low (near your hips), keep your eyes on the landing area and your body straight.
You will fly.
Don't pull the rope, it pulls you forward, off edge and releases your energy (tension) in the rope. Let the boat do the pulling. You simply stay in one position and build tension as the boat moves forward faster than you do.
Ask someone in the boat to watch the rope when you leave the wake. If the rope is tight, you're doing good because it means there's tension there. If the rope is slack, that's bad and you've come off edge loosing all of that precious energy.
