Direct copy from a previous post of mine last month:
As someone who just coached a friend from not ever skiing to running the course at 15 off at 30MPH in 9 months you need to forget the course for a bit.
I made my friend run drills for weeks at a time. Pull out, coast and cross the wake. He wasn't allowed to attempt the course until his wake crossing was solid. Trying the course too soon will only make bad habits worse.
My advice. Get out of the course, slow the boat to 26-28 MPH and work solely on crossing the wake. Focus on starting your cut in with proper body position. Hips up, handle down, stacked and connected across the wake. Forget about your turns. Once you can nail the wake crossing turns will come.
I know it is not what you want to hear, but it will pay off ten fold in the long run. I know I hate when I am told to get out of the course and run some drills. I promise some good drills and muscle memory will make the course much easier in the long run.
Extra:
You are close to getting a stack down, you had a few good cuts. I would like to see you bring rock solid across that wake every time. Doing some drills and practice without the buoys will make that much easier to learn.
I see your shoulders coming forward at the center line almost every crossing. A solid stack will stop and that keep you feeling way more stable into the ball.
