Shorty, If the hybrids of maleGSF and femaleBG look like your fish then I want to produce some for myself. I do not understand where the tanish brown blotches come from on the gill covers of your fish.
My most recent fish distribution map (Atlas of NA Freshwater Fishes) shows an isolated pocket of pumpkinseeds in the SE corner of Nebraska that surrounds the Lincoln area.
I have a publication of Hybridization of Four Species of Sunfishes from Bulletin IL Natural History Survey -1967. It mentions that the maleGSFXfemaleBG produces around a 70% male offspring compared to the other cross where around 97% are male; thus they became more popular.
Their photo of the maleGSXfemaleBG does look more similar to your fish than the other BGXGSF cross. However, neither F1 fish looks close to the color pattern of your fish. I do say that color pattern is or can be a very weak character for identifying fish. Maybe I should take my own advice until more information is known.
An interesting point in this publication is they have a photo of a hybrid maleGSFXBGfemale resting on a scale. That fish was 6 yrs old, 12.2" long and weighed 2 lbs 2 oz.
