This stuff is amazing. My only gripe is, it's hard to cut off the ends after tying a knot.
I took it in the pond behind work and I had no problem pulling out pike after pike. With their teeth, I was sure the line would break... but it never did. I must have hooked up 7 or 8 times on a single lure and my only problem was getting my lure back. No stretching, no fraying. This stuff is great. I've been using it a week straight and haven't had a single issue. (Except for that time I got my lure stuck in the tree and couldn't get it out... but you can't blame that on the line)
If you're looking for something strong, go with this.
