To me I think all your identifications are okay except for the last two showing the large (possible BGXRES hybrid). Without seeing the actual fish this looks more like a pure BG to me than a hybrid. What features did this fish have to make you think it was a hybrid; something on the gill flap? Notice on this fish the size of the mouth - it is essentially the same size mouth as a BG. I think any significant amount of GSF or RES genetics will produce a larger mouth. The body coloration also leans more toward BG than a hybrid. However I get cautious using body coloration for fish ID especially since your fish trend toward lighter washed out colors due to turbid conditions.
