I think the best "governed" series I have ever seen was in Wilmot WI. Which leads me to agree with Donny Gentry, the only difference is they ran a 1 3/4 header, spec RR tire (which I hate) and a weight rule.
I have been saying FOR YEARS we need a series like this since the DEMISE of the MSCS series that Sam started with this same principle in its conception.
