This afternoon I looked at the Cooper A/T3's. They're more expensive than either the KO2 or Michelin LTX but they come with a $100 Cabelas gift certificate that gets the price very comparable. I'd rather have the cash than the gift cert, though. The Coopers do have a 55k warranty while the KO2's have none.
They also carry Bridgestones. He warned me about a problem with the Revos. They come out of the mold with the shoulders tapering off. He said that if you don't rotate them religiously every 4 to 5k, they'll continue to wear on the shoulders.
