Been reading (a lot) about suspension, and I have a question. I really like the marlinspike—it’s quick and easy, and seems to spread the load over more of the webbing rather than pinching it. The setup I am planning is along these lines: tree hugger girth-hitched, and a marlinspike close to the hitch. From there, the easy thing to do would be to tie an overhand on a bight to create a loop that will go over the toggle and lead the webbing to the descender rings on the end of my gathered hammock.
Because, other than a water knot, I have little experience tying knots with webbing, I am concerned that the knot created by the overhand on a bight might significantly weaken the webbing under load. My question is this: can I slip another marlinspike hitch from the webbing over the toggle from the tree-hugger, or would that cause an instability or additional stress that I am overlooking? I've been scouring the threads, but can't seem to find what I'm looking for.
I’m trying to get some Scouts in the air with materials on-hand, and I prefer not to be remembered as the guy who single-handedly paralyzed the troop (I have way too many other things to live down before I tackle that kind of debacle) . Any insights or experiences would be greatly appreciated.
