So I'm curious why scoff at holdovers, seems to me a 5, 10 or 15 lb holdover isn't any different than a 5, 10 or 15 lb fresh fish. You put them both in the same conditions, same water temps, same weather and tidal conditions and duh, they both act like stripers.
Just because they are suddenly fresh and moving north, what that then makes them a worthy target. It's my brand of ice fishing and keeping myself fishing, I think someone has issues.
