HBG F1+ genetic expression gets pretty hard [for me] to ID - but I also tend to lean towards Bill's call - if I had to wager I'd say either GSF/RES or HBG [GSF/BG] x RES. I don't think I see any BG characteristics, so likely the former?

Take heart Luke, I think naturally occuring F1+ lepomis hybrids are really cool - sharpens your genetic discernment, leads to sometimes exotic/stunning specimens, and likely has low risk regarding recruitment, etc. Throw in the hybrid vigor factor and I'd just keep sampling and posting your beauties for our collective enjoyment!
