Ok then dont handycap the people that do their own work. They have to many rules to help the crates. No one said that you had to run a crate, but since you do you need rule to bring the other guys down.
I would say the playing field is pretty even considering a stock car can't safely get down to 2600 and have any chance of also scaling where u want it. Also I haven't seen anyone come across scales under 2700 so the rule doesn't seem to have the any effect...
