Allen does, he shared it during a class he was teaching at Midwest. He used like 5 25' bungees from Harbor Frieght ( now there is a suprise, I think he is a paid spokesman for them sometimes). Maybe Allen can post some pics for you showing it. It sounded cool and I did buy 10 of the bungees for it and they we cheep if you order on line ( 10 because I am fat and I may get the crazy idea to try it out) I have not put the rig together myself but the most expensive part is a good harness. Good luck
