Is there any practical difference between the Hangman's Noose and the Uni Knot (a.k.a. Duncan loop)? The difference I see between the two is that the coils are wound inside the loop in the uni knot while the coils are wound outside the loop in the hangman's noose. Does this difference in configuration affect the knot's strength or proneness to jamming, slipping, etc?
I plan on using these knot to secure a line to a pole which will bear some load on the other end (think of a cantilever roofing with ropes attached from the vertical wall down to the end of the roofing to support it). I prefer using one of these two instead of an anchor hitch or some other hitch since these two knots are in a way adjustable.
