Locking onto the pulling edge way past center line (at shortline) is simply inefficient. To ski the handle path its essential that you transition early around center line, if you can think of being high on the boat rather than wide and being on the inside edge early it starts to make a lot more sense, easier said than done when your out on the water. I think problems can start when skiers progressing through the loops think they need to pull harder / longer to reach the buoy line, any efficiency they have goes out the door as they go to war with the boat so they try / pull harder, the movement they should have though the center is muted by a whole lot of pulling force and gritted teeth and so the transition is often much later as a result. In my opinion you have to learn to trust that 400 plus HP is more than enough to get you out there, do your job from hookup to center line and then learn to use the energy from the boat to get the height / width you need.
