Pro and Amatuer classes would still keep the atmosphere and the level of competitivness relatively the same wouldn't they??
I think alot of peoples concerns are because it would be a "NEW" thing. I know it's been done before, but I'm talking about a new standard. I think it would have growing pains (PRO classes that were actually PRO/$$ classes at every event) over the first few races until the newness wore off. Then it would mellow out I think.
