Yeah LMB that size/numbers would be good. I'd fish it some this fall just to see if by chance something is in there besides the sunfish. Your stocker bass would be expensive snacks if they aren't the biggest fish in the pond.

For now I'd determine what sunfish species you have and then stock BG or RES if you need to. If you end up needing to stock them I'd stock the biggest ones you can find. Numbers depend on the size you can get.
