I was just wondering if any of you are using superlines, like Berkley Fireline? I have used it for jigging walleyes, bass and icefishing. I just bought some 3lb crystal fireline.It has a 3/4lb mono diameter. I have always used 4lb mono but want to try something with a smaller diameter. I'm looking for less visability and more sensitivity. The rod that I have this on is a 6ft one piece St.Croix UL that I built myself many moons ago. It casts great with 4lb and is very sensitive, but I'm always looking for an edge!
