I've used beaver dam tipups for 25 years, the best made in my opinion, the only reason i'm not still running the first ones I bought is they were stolen...grrrrrrr. The spools aren't the largest when thinking of lake trout in deep water as we don't have that kind of fishery in MN. Best advice on line is to use the nylon coated.....any non-coated line is just a windknot, line freezing mess. the more line a fish takes the more problems a guy has pulling in the line, respooling up.
