A good excercise for technique is this:
1. Edge as far out as you can toeside.
2. Flatten out, letting the boat pull you back towards the wake.
3. Set your shoulders, hips and feet to the angle you are comfortable at, with the handle at hip level. STAY IN THIS POSITION!
4. Slowly edging towards the wake, pop up and over the first wake, land, then up and over the second wake, and edge all the way out to the other side.
Did your shoulders stay in position? when you popped up over the first wake, did you land on the same edge you left the top of the wake at, or did you come over on your toes and have to reset before the second wake?
If you have improper form, it is surprisingly hard to pop of each wake on this path. when you can do it, your w2w form is where it needs to be.
