Backscreen,
I will say that here in the IHSA, we have a technical area, both teams are on the same side, usually have a 3 man system until you get out into the small schools, have a referee rating system, and if anyone is warming up they are in a penny....sounds like the SCHSL needs to step it up and provide you all with something quality.
I do find that it is much easier to have the players on the same sideline for substitutions, and it is nice to not have any parents or anybody else sitting behind the players. We don't allow anyone behind the benches here....much better in my opinion.
