What is your biggest Flathead? And just for fun, what is your biggest fish other than a Flathead. My Flathead is 43.11 Other fish, I caught a 40 pound stingray if that doesnt count, I caught a 37 pound Mahi Mahi or Durado. I think it would be cool for us to set up a list and to update it as we get bigger fish. What do you think?
