Yes, I do. I ran my fastest two events on the last time I ran both sets. The 60 run set I ran the fastest run ever on those on run 58. On the 106 run tires, I ran the best on run 106. We only started running the newer set because like you, it sounded crazy to go to the Finale/Nats on 106 run tires. We should have as sticker tires are arguably a little slower than 30+ run tires.
SP+ classes don't count. They belong on race tires and you have the needed adjustability to get decent life from them. We are talking about Stock class only. I don't want total thread derailment here but seriously, I'm not crazy, I wouldn't want to go this route if I had not experienced this for myself.

I understand your biggest issue with my comment is related to the longevity difference between RTs and R-comps, and I am fine with putting that debate to bed. I've just had contrary experience, I haven't run street tires since around 07-08, we used to run the 232 hankooks as well as the Advan Neovas, both of which used to be shaved, and we didn't get any better life out of them than I did on R-comps. From second hand sources, I've been left to believe that is still the case in many vehicles instances related to the R1R and the RS-3. I'd be concerned by pushing RTs to all stock classes, in order to set their tires performance apart, you will see tire life deminish back to the point of lots of tire shaving and still autocross specific compounds, it just wouldn't solve anything long term.
Also FWIW, we are within OE specs for alignment, and with double-wishbone even with the stiffer suspension and less used travel, we didn't significantly alter the tirewear characteristics (aside from dumping gobs more torque and HP out back.
