@dnewton in your first post you mention "can't get the ski to turn offside". Keep in mind I'm at the same stage as you are, learning 28 off. I see similar things in your video as I see in video of myself and what I feel is that if I'm on the back of the ski it doesn't turn offside. I see your hips going over the back foot during your gate glide & turn in and they stay there the entire pass.
There's many ways to say it and lots of discussion on this forum about getting your hips up and really focusing on that part of your skiing will help throughout the course.
Straighter legs
Proud chest
Shoulders back
Push hips to next ball
etc
Find a thought that works for you and gets feet, hips, shoulders lined up throughout the course. When your weight is balanced between your feet the water should be breaking at the ball of your front foot or even farther ahead when in the glide.
When I'm not stacked behind the boat I think about re-stacking from the wakes to the ball just like in the gate glide. Re-balancing weight on both feet as you head into the ball will get your center of mass forward in a strong position for the turn and load after the turn.
Establish stack during glide and wakes to ball
Keep stacked behind the boat.
You're looking really good especially how well you finish the turn and set angle before loading on the rope. Great Skiing!
