Some food for thought:
Springboro 818
Miamisburg 632
Franklin 347
Bellbrook 320
Monroe 330
But yeah Franklin should be lining up with schools double their size... Should they be playing Madison, Carlisle, and Shawnee in football? No I agree but saying to go play a school thats in the top 25 in the state in enrollment is not the answer. They played both Springboro and Miamisburg in the past decade as well.
I want to see big school expansion in the SWBL. Add Edgewood, Talawanda, Ross, Massie, and Wilmington and it'd be a hell of a conference on big and small side.
