Just out of curiousity, IFF, why do you use it? I fell in love with Trilene Hi- Vis for open water a few yrs ago, respooled all my bass/pickerel reels with it. I could always see where I was casting or trolling. The following year it was (and still remains) impossible to find. Guess I was the only one who liked it. It was very bright chartreuse in color.
What advantage does hi-vis have on ice?
