I'm new to rope-climbing, I have made some slings to use as false-crotches/cambium-savers/friction-savers that act as my "canopy anchor" when climbing. These were all made with lengths of my 11.7 mm climbing rope (anchor-knotted at the ends to aluminium O-rings)
But then I noticed an auto-lifting sling: 2" flat webbing with 6k break-strength / 2ton working-load; each end of this 7' sling has sewn eye terminations. I am thinking that 'choking' (girth hitching) this sling around a natural crotch in a tree would be significantly superior to comparably-rated rope, due to the shape advantage of being flat instead of round. I just wanted to verify that I'm on-point before I start messing-around climbing it. lol ;D
(FWIW I'd treat it like anything when using it, starting very low & slow to feel it out!)
