Sean, if your stocking plan included HBG, it doesn't matter where you buy your fish IMO. I know that there is one of your neighbors thst love them, but I also have a reliable source that tells me they just delivered some of Overton's pure Florda CNBG offsprings recently.
Why would any one stock any other than the very best CNBG genetics in our area. Overton may be higher cost than others - I don't know because I don't shop around. I trust Overton to hatch and grow the best quality fish available anywhere.
He does not sell and will not sell HBG - go for the fish truck if you want inferior fish... IMO...
Best of luck,
George
