Cut through wake or flatten out?

Im trying to work on getting more pop and more air off of my jumps. One thing I dont quite understand is if I should be cutting all thr way through the wake so that I am pushing off the lip with my edge dug in, or if I am supposed to flatten the board as I hit the wake (snowboard like). Also, how perpendicular to the wake should I be? Should I be hitting the wake straight on (again snowboard like, 90 degrees to the wake)or will I be angled at the wake.

Thanks
Nick
