Here would be a great test.
Walk in to Gander and they are having a sale on tip ups, all are $20 each.
They have a truckload of each.
Jack Traps, Heritage Lakers, Beaver Dams, Polar Extreams, Slammers and a few others.
I would be willing to bet the Jack Traps and Heritage Lakers sell out first.
At $40 each the BDs will bite the dust quick!!!!! They are a good tip up but they don't command the top dollar in mine or alot of other's books.
I have been doing this hardwater fishing for 45 years and had or have them all and it just does not make any sense to me.
