Pop!

I would like everyone’s opinion on getting pop. After watching my video (higher education), they tell me to keep my progressive edge through the wake and straighten out just before I hit the wake. For some reason I can'/won't extend my legs all the way before I hit the wake.

But when I flatten out my board at the wake I extend my legs more and get a lot more pop. From what the video says this is bad. I know I loose some speed but if I get a lot more pop this way should I do it anyway or can someone give me a magic trick to make my legs lock while holding my edge.

Thanks for the help.
