So I ended up redrawing all of Ohio's legislature for both houses. I started for basically two reasons, to get a feel for how the layout the state skews the partisan numbers, and to experiment with grouping three House seats into one Senate. The latter is actually a tad tricky, since you might have an area that's an obvious community of interest and has seven districts, but one has to be left out, and you end up with some awkward Senate districts. But those will come later. For now: House.
Just because Ohio doesn't follow their constitution is no reason for you to not do so.
The Ohio Constitution rules are terrible and internally inconsistent anyway. Not worth trying to follow.
