world record large mouth is just over 22 pounds, people catch 15-20 ponders everyday, so if you keep one expect it to hit well over 15 pounds, but it takes many of years for them to get this big. i actually watched a video the other day with a guy that hooked into a 25= pound large mouth, but when they went to net it, it broke the net and the line.
I do not see how you could even make such a claim seeing that you are from a state where only the Northern strain LM Bass can live and I dont think there has ever been a recorded case of a Northern that big. Lets see the link to the vid.
