Why fool around with anything other than Bluegill? Seems like the hatcheries in your area would have the native northern strain acclimated to your neck of the woods. Our place is virtually straight due east of you in west central Illinois. The fisheries biologists here all recommend BG as the foundation and really the only thing you need if you can manage them properly (they are low maintenance).
We also have golden shiners at our place but we have found them tougher to manage. Their population swings up and down way more than the BG population. We needed "no brainer" forage at our place and BG have met that need very well. They spawn 2 or 3 times each year in our area. Maybe get the BG foundation going and well established and then experiment with another forage choice. Just my pondmeister in training 2 cents. BM61.
