I spoke with Andy Hurdman at the beach yesterday about how he does this move ...

1. Andy said to get going powered up and moving out fast, ideally toeside.
2. Start to send the kite as if you were going to jump but go more slowly.
3. Lean over and boost your legs up while hanging off the bar.
4. Drag your hand and try to maintain kite position overhead but slightly foward as you slowly rotate along the run.
Easy right, NO, I suspect not. That is a start however for guys that are up to experimenting with this. Be careful and have fun!
I hope Andy jumps in to add some more detail to this ...
