Just a sidebar on the Heritage Laker T/U thread. If you haven't ever used these magnum sized tipups, you should give them some consideration. I thought they looked big and therefore, hard to set for light hits. These units can be set for hair trigger strikes or to hold the feistiest of chubs. When you get a fish on, you can set them top-side down and the reel stays off the ice and prevents a flash freeze of the line to the ice which nearly always results in lost fish or damaged leaders. I finished 4 of them 2 years ago and they are in perfect condition. The fittings are brass and these have an adjustable drag to avoid backlash spooling on fast running fish. When the flag is up, they are 42" in the air! Easily visible in deep snow and to vehicle travel (how many people have lost thermal frabils to trucks?). There are times and places for thermals and magnetics and such...but for the hard conditions of NE South Dakota and the upper Midwest in general, these are a great option. Couple them with artic sirens or lighted indicators and they are a blast at night.
