I like SpiderWire..I use 80Lb test..I have pulled up 14+ ft logs with it, towed a boat with it once. It is light, strong as all get out, light, easy to use. A guy I fly with wasn't convinced of it's strength..I tied some directly to a DuBro large control horn. Put that in a vice, tied the other end to a hammer handle. Pulled the SpiderWire thru the control horn. When fishing with it, if you get hung, you cannot just wrap it around your hand and pull, it will cut you to the bone before it will break. It will sure as heck strip the gears in any nylon geared servo before it breaks.

Just my experience...this is the aramid braid, not the monofilament BTW
