The other post about leader length preference for Jigging got me thinking about this. I have always kept my leader very short (less then 5 feet) when Popping for Tuna. I have done this because I don't like passing the knot through the guides while casting. What do others prefer? I know that a longer leader is preferable, but what about weakening the knot while it passes through the guides? Does a PR Knot prevent the weakening, or at least cut down on it?
