What line length are you riding at?
Sometimes if you come in 5 feet from where you are riding at now will help you clear the wake,
especially if your that close to making it all the
way across, and then as you progress are landing in the flats, let your self back out 5 feet. Nothing wrong with starting in closer to help you get that feeling of clearing the wake.
Of course make sure your standing tall at the top
of the wake too.
