Kevlar, while being a super material for body armor, and boat hulls, fails miserably at abrasion resistance. I tried the Sullivan Kevlar cables, with the supplied Sullivan hardware. After what seem (at least to me) like an abnormally short period of time one of the Kevlar cables let go. The end that was in the Sullivan hoop had frayed and broke. I went back to what I had been using for many years with no problems, nylon coated fishing leader.

Kevlar, like that other DuPont product Teflon, has been used to hype many a product, some benefited from it, some didn't.

There is one brand of coated Kevlar cable that seems to be doing OK in our hobby, but I can't remember the make at the moment. It has a coating on it that prevents it from rubbing on it's self, kinda like nylon coated leader wire.
