Sorry, was out of civilization on a hunting trip in Bedford County, PA...
Anyways, I think RBS are the best candidate for a sunfish in a SMB pond. Although, they will not get nearly as large as BG, they will commonly reach 8" and some will push past 10" and 1 pound. And for anyone who has caught them, they fight like champs. They are a bit more fusiform than BG, making them easier for SMB and HSB to prey on. They are also far less prolific than BG.
They are commercially available and there is a golden morph variety as well similar to the golden rainbow trout in coloration.
