I was just checking out the advanced tarp article and found this technique
"Guylines can be pre-tied with overhand, figure-eight, or bowline loops in each end. They should be about two or three feet in length (which minimizes tangling during storage). Longer guylines can be made by girth hitching multiple short pieces together. This gives you a very flexible system for pitching in a variety of configurations. Once your guyline length is set, simply girth hitch one end loop to the tarp’s guyline tie-outs, insert the stake in the other end loop, tension the guyline, and set the stake. Tension is adjusted by resetting the stake, rather than fiddling around with a tautline hitch, that artistic adjustable knot so prominently showcased by the Boy Scouts as an essential skill. This is where the benefit of titanium skewer stakes really shines – since they are so easy to place and remove relative to other types of stakes, this guyline-and-stake system used for tarp adjustment is simple, fast, and effective."
This sounds like a great system and is similar to how I handle leaders when fly fishing except I use what is called a perfection loop (same thing?). Does anyone have any experience with how well this works? What are the pros/cons of this system vs having different length guylines on hand? It sounds really good but w all know how that can go.
