I agree with you Andrew as far as my dealings with em.
Bluegill/Redear and Bluegill/Green have been my only experience with hybrids.
However after catching tons of what I thought were Redbreast or even calling em juvenile Redbreast I was wrong.
I showed numerous photographs of these fish to both Parks&Wildlife and to Marine Biologist in the private sector and they have identified them as hybrids.
I also have 8 "Hybrid Records" in the books that two years ago I would have called em Redbreast.
Anyway for each their own.
I do know one thing for certain. They are super good fighters no matter what we call em.
Stay dry out there. We got some more heavy rain coming in this upcoming weekend.
