Cumberland had some a few years back. Caught several myself. Haven't seen them in a while. I think the spawns have to line up just right. Everything I've read says mean mouths in KY are to be treated as smallies.

I'd have to say that I would disagree with this. It's going to be a hybrid that can not reproduce. A 17" hybrid mean mouth would be a trophy worth mounting. The one's I caught were in the 15" range so they, of course, were released.
