Are your shoulders behind your hips when you edge?
I use to edge super hard but could not build pop. I was hitting the wake with shoulders in front of my hips. This will cause you to hinge forward and loose pop. Build the line tension, fight the boat, shoulders behind hips, 45, and push down as you ride up the wake. It is one of the most difficult and critical elements to learn in boarding. I wish I could do it right all the time, but that's a work in progress. When you land a trick it's typically because you started off right by good edging.
Me, poor edge, shoulders almost over my knees(not even a good spray) zero pop all speed landed in the flats-no good.
Jamaican- this guy edges like Shapiro
