I have been working with 3 college kids learning to slalom the course. They all try to crank the turns at 15 off and then pop up behind the boat or can't hold edge through both wakes. When I get them to focus on easy turns finishing with hips up and lock the handle into their waist and lean away with straight arms, without exception, they run easy passes. I keep telling them you run long line passes between the wakes not the turns.
Anyone out there struggling with the same affliction? Try it and see if it works for you.
