I had a hard time getting consistent pop. Here is what i have figured out in order to land wake to wake every time. You dont have to edge all the way out, just take a nice progressive edge in, letting the boat pull you into the wake. When you hit the wake stay on your edge standing up away from the boat.
HANDLE POSITION is very important, dont let the handle get to far away from your body. I try to keep my elbows tucked in at my side. Another thing is to hold on with both hands until you leave the wake. If you are letting go to early you will loose a lot of power in your pop.
hope this helps
