You simply need to remember with this stuff that you are not dealing with a line that has a core. You are working only with the 'core' and when it breaks, it's gone. It takes amazingly few broken strands in a single braid to lead to a severed line.

Of all the lines that I've used (vectran, amsteel, etc.) the amsteel has proven to be the most wear resistant. I currently have some 1/4" weird coated vectran stuff on my trap lines that Trey showed up with one day...but come to think of it, that stuff still looks really good after a year. So ... nevermind.
