I have been using this on my hiking setup to save weight and it is working well. The wrap for rope is different and I use a couple half hitches for safety. I did not sew the rings into the tree hugger. You can loop one end of the tree hugger around the rings and this helps tighten the rings more than you could when sewing.
yeah, its just like the ring buckles + webbing, the wrap is even the same i think. wonder why no one figured it would work with rope as well.
it should be considerably lighter. 15' of webbing is alot heavier than a 7' tree strap and 8' of spectra line. (same total length)
