bflat53212, you are right I definitely threw my head down on my front knee. I thought about throwing my head down on my back knee before, just as what you said. I think I would definitely have more line tension and my board will land with a better angle as well, thanks.
Robertr720, I definitely need to let go of my rear hand and I know I didn't pop at the peak of the wake. I would have gained a lot more height if I had done so. It has been difficult for me to delay my pop. I do the same for my HS backroll. I wonder if there's anything to do to kick the bad habit???
