Learning to pump

Pump/Wake Foil

Hey dudes/dudettes,

Last summer I bought an axis PNG 1150 w/ wake thief foil setup to pump or ride behind a boat in small wakes. The problem is that I cannot get the hang of it. I built the PVC dock launcher and have tried getting up behind a boat. Are there any good resources for learning this the right way? A step by step or something would be incredible.
