I had the same trouble this year - it's my first season having any clue - So when I cut, I would ease up and basically be "pulled" instead of "pulling" into the wake. Does that make any sense? Anyway, the process would throw my feet behind and as a result, a good face plant would follow. Luckily, my girlfriend was usually the only one to see it.
Anyway, a friend pointed out to cut hard and stand tall off the wake. Huge improvement.
