Not to hijack the thread, but I love spiderwire, firewire, or gorilla wire too. I've found the 100# test stuff strong enough to lash poles for a leanto, bind a gaf hook to a pole to snag fish in a survival scenario, and many other uses. You absolutely can't break it in your hands, without slicing through a finger like piano wire would! You may need to try different knot styles.
I put a tiny dab of hot glue on my pencil stub, anchored the line to that, put the pencil in a drill chuck and ran it as slowly as I could. Was able to lay down yards and yards of smooth, tight rows.
