Berkley Trilene Micro Ice. This is the line we use when ice fishing for panfish. We use the clear steel most often. We use the solar green when hole hopping outside of the shanty. The solar green is easier to see light bites, especially when it's windy. We typically use 2# in the shanty and 3# when hole hopping. The 3# line holds up to the elements better as the holes are freezing over, etc. Sold per each.
