The thing is this; no matter the enrollments of the schools at a sectional, they will all wrestle each other throughout their state journey.
If you are suggesting to make a “big school sectional” and a “small school” one, then we are essentially making pseudo-class wrestling. Even with this “solution” the small schools will still eventually have to wrestle the large schools.
If it’s an argument against big schools winning the sectional due to their size, just look at Mater Dei. They win sectionals and regionals despite being a smaller school.
