From the responses you see the most, Joe Pool seems to be about as good as any. I live north so I fish Lavon primarily, as well as Hubbard and Lewisville. I think bluegills stop growing at 5" in those lakes
I've never caught a bluegill down here on a minnow, and worms seem to produce catfish and small bass. Fly fishing I can catch a ton, but only fun to catch size no eaters. Good luck!
