I've been ice fishing with vicious for about 10 years now. It used to be really hard to get and I would hoard it when I could find it. 2lb and 4lb is what I use on my ice rods. 4lb and 6lb on my summer rigs.

I use Hi Vis during ice season. Makes it so much easier when you can see the line. Both on the ice, and in the water to detect the soft bite. For soft water, I use both the hi vis and the clear. Some days they just don't seem to like the Hi Vis stuff.
