I never did try this but hope to soon. I can use my SRT climbing line, as is. I need to make up a foot tether.

I can confirm that girth hitching works. A bit snug with sneakers, but OK.Girth hitching it works and I think Scott Adkins does. His videos are a must. I originally had the carabiner in there because I'm a nut for safety and was using it as a second tree tether before I switched to WorkPro. Oplux is plenty strong, it was just me. The foot loop is made from a old pack shoulder strap and 2" webbing with 1/8" stretch cord like Scott did it. I'll probably take the carabiner out.
