Just a couple of thoughts:
I have run Chumpcar in a Mustang that had 28 hours of racing (two 14-hour events) on a set of Dunlop Direzza tires (200 treadwear). Granted, being endurance racing the racing was not 100% pedal down but the tires still felt great and after 28 hours still had tread left. I was very surprised at the amount of grip the street tires had.

I like the idea of the NT01's b/c you wouldn't need to shave them and they are cheaper than the RA1's.

Toyo wants to make money and sell more tires. I'm sure they wanted a tire that didn't last as long as the RA1 so they could sell more tires and make more money. Mission accomplished for them, bad for us.

I think the easiest solution for the time being is to go back to the RA1's. I don't have any data but would guess that a 10-heat cycle RA1 would be faster than a 10-heat cycle RR. The brand new RR would have the advantage at the 1st event but after that would not be worth it.
Who knows, just thinking out loud.
