It is one of the better Co-Polymer lines out there, not sure what co-polymer means exactly but it seems to hold up to abrasions for its size a lot better then most mono lines. I think I recall a couple of Flathead guys turned a couple of us on to it. They use it a lot fishing for very large and powerful fish that like to make homes in the nastiest log jams you can find.
Not saying it is head and shoulders better then anything else out there, but for the price, if I was faced with landing that fish of a lifetime on lighter lines ( I don't use heavy braids except for shock leader ) I would feel a lot better with mean Green on.
