I have a mix of pure Floridas, pure Northern, and F1s. Probably will stock a new batch of F1s every 2 or 3 years. So far my largest is only around 7 lb, but strongly suspect bigger ones are deeper than we usually fish. CNBG are in very good shape due to feeding, threadfin shad, tilapia & golden shiners also stocked, so there should be plenty of eat. Maybe the addition of artificial habitat will concentrate some of the bigguns where they can be more easily caught!
