RE: Spiderwire
Spiderwire Fusion is much more fragile than any of the stranded versions. It will break easily at a knot if the plane gets loose on the lines and hits the edge of the circle.
All the Spectra(tm) fishing lines I've tried are way over-rated for pull test. I've tried at least 6 different brands of stranded Spectra(Spiderwire, Gorilla Braid, Pro Line, Tech) and they all break at about half the fishing rated breaking strength. So 25-30 lb. test is about right for Half A's.
We tested several ways of making the ends. They all worked about the same. A simple loop tied into and overhand knot, a palomar knot, and crimping the lines all worked. The line generally broke at about half the rated strength a couple of inches from the knot.
