I understand. I do pretty much the same thing.
I went and looked at this year's Top 10 of One Lap of America and noticed that the 8 of the top 10 finishers overall were running Michelin Pilot 4S - the other two were running BFGoodrich Continental ExtremeSport Contacts.
I just wish Michelin would make a summer tire for 15 and 16" diameter wheels.
For performance work it's all Yokohamas around my house, since I sold my last car with 18" wheels 5+ years ago. For all seasons though, the Michelin Defender reigns supreme.
