You were told correctly about hybrid bluegill, Travis. They're only desirable for the first generation - subsequent generations, i.e. their offspring, regress genetically so that most of their growth potential is lost. And, common northern-strain bluegill will get bigger than hybrid bluegill if they're fed pellet food. But best of all is coppernose bluegill, which are a substrain native to Florida. They're the bluegill equivalent of Florida largemouth - they grow faster and get bigger than northern-strain bluegill, and they're not a hybrid so there's no genetic drop-off from generation to generation.

And I just happen to be raising a bunch of pure-strain coppernose bluegill in several smaller ponds in the area, and will be stocking them in both association lakes

And yes, the bass in the trophy bass lake will be quite a handful on a fly rod in two or three years...
