Re: Q about backing
Just to clarify, monofilament is in fact nylon. Many "monofilaments" nowadays are actually a copolymer that have multiple materials in them, but true monofilament is nylon. The most common material used for flyline backing is dacron, a form of polyester that doesn't stretch much at all and lays flat when wound onto a reel.
I'm not trying to be a turd, just don't want our "new flyer" to stand there looking at a box that says "nylon monofilament" and be confused by what we have told him.
