Not sure I explained it right
It's sort of part of a Jacobs Ladder, except instead of giving a tug to yoyo into the fade, you give it slack so the nose drops and you're wrapped up.
Just another way of wrapping the kite up.
If you do it fast, it appears as a lazy to wrapped nose dive. You can then fly around wrapped up as normal OR go straight into a 540 and unwrap.
