2# green Tri-lene for both ice fishing and open water. Went down to 1# once, just couldn't see it to tie knots. If I can't catch em on 2#, they can stay in the water. I might have to change my tone if my eyes keep getting worse, 3# might be in my future, lol. Buddy of mine uses sewing thread, he told me I should start using it. I looked at him and asked if he would tie my hooks on for me. He just laughed!
