Not that my opinion means anything here since I am not currently racing, but I think everyone has a point here from both sides.

1. The RR is not a great tire for CMC. Overpriced and doesn't work well with a budget minded series. No one likes to get beat specifically by another persons wallet.
2. However, for racing CMC... it is your only option. You could all agree to race AIX regionally, but not everyone would do it.
3. This group can't just decide to change tires since it is a national class. I think Michael agrees with you that the RR is not the ideal tire, but some folks switching and some not is not a great solution either. While it is easy to say everyone should change, the reality is much more difficult and some wouldn't do it.
4. I am not sure NASA gives a crap that you don't like the tire... they are getting paid by Toyo.
