Just follow the progression: load & pop, hooked-in raleys & back-rolls, then go unhooked. (...)
If you're used to riding cable, I wouldn't waste time on learning to pop hooked neither. To be hooked in just give you a weird centre of gravity that you're not used to from the cable. On a good day I'm doing front2blinds and back2wrapped with the kite, but I still don't know how to pop properly when I'm hooked in. Good luck, you'll progress fast, being used to pop in the cable!
Any tips for a fairly experienced cable rider for moving cable tricks to the kite? I'm talking anything from kite position/control, edging technique, etc. (...)
Go with speed, kite steady at 45 degrees or lower, edging and loading for a shorter period (more like a determined carve, rather than longlasting edging). Slower speed and kite at higher angles can be good for soft learning, but definitively affects the style and flow of the jump.
