I use the HSS vest, but I use it with the rope and prussic knot that came with my Summit Viper. I second I step onto the platform I adjust it around the tree and hook up the strap in back As I move up the tree, I push the rope up over my head as high as possible, then climb to it. I don't use the lineman's belt set-up that's hooks at the waist, I found it to be too much of a pain the a$$ to deal with.
