Try taking a more progressive edge for your cut. What I mean is to take a slower turn in towards the wake and build your board angle from start to finish of the turn.
You should also try standing taller THROUGH the wake. You suck up your knees a little early. If you stand taller and suck up your knees AFTER you've left the water you will have a tonne more pop.
Send me an email if you want some more pointers. I used to coach a wakeboard school here in Canada. Now I am stuck in the store and not out coaching as much but I still love to talk wake. If you show me some more video I would be more then happy to have a look at it and offer some feed back.
