As I live close to the Ky line in Tennessee I have also asked the same question and had a couple of hatcheries to tell me that the intergrade northern florida cross should do a lot better than pure florida's. Isn't that what an F-1 is? Good luck; I would love to eventually stock bass with florida genes in them. I know the TWRA is stocking Florida strain in Tennessee but only south of a semicircle that goes from around Memphis over to I think Winchester but a little further south. This area is at least a couple hundred miles south of me and that much further for you.
