Ours is about 50/50. Those on a budget or doing 20-30 events per year are looking at the RT660's. People who are really gunning for times or have cars with enough camber to not totally chew through them are going A052.
The A052 tends to not take the heat well. If you overdrive it, you can also scorch through a set very quickly. Like 30 runs quickly. Yet I've seen others go 150 runs on them surprisingly.
The RT660's are basically a refined RE-71R. They might be a hair slower or right on par, but have been showing not to heat cycle out as quick. It seems like RE's are downhill after 60-70 good runs. By 100, you have tread, but the compound is getting hard. 660's are looking like they are more or less good to the end of tread.
