I have no issues with meth and we will probably convert to it next season for the reasons you stated above.

The best thing to do with the bigger motors is to 'grandfather' whoever has one. They all have serial numbers....make the ones legal that are currently running and move to a spec 1000 for anything new.

Make traction control systems / fuel injection systems illegal....that can be easily teched.

I have no problem with the 950 pound rule. We are at 930, so it would be no big deal to throw a 25 pound weight in the car.

Keep it cheap and simple.
