Having looked at all the uses of the Whoopie and UCR I thought I'd look at lots of othe uses for constriction and I came across the Loopie sling on an arborists forum. Similar in concept to the Whoopie, although slightly different construction, more like a loop made using an inline UCR(Loopie Pic). The use of these slings by tree specialists is slighty different to how they are used in hammocking, but I can see uses for both (Loopie use & Whoopie use pics).
I have been studying the idea and knocked up a mini version in some simple nylon braid of a possible adjustable ridgeline for my single line suspension here is the thought (Loopie adjustable ridgeline pic).
Before I make this up for real, does anybody have any thoughts as to holding power and possible accidental slippage.
