TNBronzeback, I would hazard a guess that Bill Dance has F-1s in his lake. He does not have a pond management company himself, but there is one out of Alabama that he has allowed to use his name. That company is one of my competitors, as of course is whatever company that is managing the lake Alpha alluded to. I'm a smaller company at present than many of the pond management companies that do business in this area, though one major difference is that I actually live here, whereas they all are coming from out-of-state. Sometimes it seems like they are worried about me, just judging from how zealous they seem to be for keeping me from getting a foothold
The reason I would guess F-1s for Bill Dance's lake is because those fish still hit lures reasonably well, but they get too big on average to likely be northern-strain. I managed a 56-acre lake for three years, the first year of which we stocked F-1s (we also did a couple other things to improve the bass fishing); when I took over the lake, according to the owner, the largest bass that had come from it was six pounds. Three years later, in one afternoon and the next morning of fishing, two anglers caught thirteen bass between four and nine pounds each, including six that went between seven and nine. I have photos of several of those fish; some of them are on my website.
