Yea my local lake lost its southern strain bass population to the northern strain. They didn't like the clear cold deep water of the reservoir where the northern strain and small mouth thrive. The lake where I caught those sunfish still has florida strain bass because it's shallower, murky/warm, and has a ton of shad. I saw two 6-8lbers that day, one grabbed my sunny that I had just hooked and ran with it before spitting it out. She came back to chase the sunny but missed it close in. Again, nice fish, from my lake the northern strains rarely pass 5 lbs.
