My dad has a couple mounted that his dad caught years ago.....I don't know how much they weighed, but they're hefty. They're also more greenish than the silver ones you usually see around here. Think they came out of either Sardis or Arkabutla, but I won't swear to it.
This is the only pic I could find of them.....the top one is significantly bigger, but it's a bad angle of that one. Don't know if it'd go 3 or not, but still bigger than any I've ever caught.
