Coast back toward the wake. Let the rope gently pull you then:
1. Drop your butt
2. Drop your elbows to your side
3. Hold your edge till you get to the top of the wake.
4. Stand tall at takeoff.
By the time you get to the wake, you will be at maximum speed, angle, and edge. You will sail.
Better keep a tight puul on the rope. If you let your hands drift away, you will crash hard.
