I don't really fish recreationally, so I don't have a whole lot of experience.

When I was thinking of what to add to a PSK re: fishing and food gathering, I've been using braided heavy test line (65 lbs), the line of thought being it could be used for fishing but also for light lashing.

Is there any reason to go with a lighter test monofilament line as well, or should the braided line suffice?
