The flounder, as already said, are tough. Being flat and trying to lift them up, that works in their favor. Don’t forget the teeth and attitude. A 15” will give a good fight. I got one last year that was 22” and it was a super fight. When they decide to go there isn’t much we can do but hold on. If you ever get to a GOOD seafood restaurant and they have fresh stuffed flounder, I urge you to indulge. One of my favorites.
