My ice rig set up for my rods usually is 4lb with a 2 lb leader. (I'll vary the kine of 4 lb line & 2 lb line between manufactureres and brand). My 2 lb Polaris line sure is limber and breaks so easily, I'm skeptical of using it these days. What's your favorite ice rig line setup? have you ever fished with 1 lb or 1/2 lb line?
