I do a tail grab and just tweek the shit out of it, works best for me. Just find a grab that you feel right with when start your spinning and work from there. Props to all the progress you have done this year, your videos are great to watch maybe you need to make an end of year recap.

Wouldn't it be a seat belt??? front hand to uphill binding as this would lock the shoulders into the rotation and better allow him to keep his head looking into the rotation, allowing him to spin completely around???
Never done it just trying to visualize the motions...
