Heck the Bill Boards aren't that bad, I'd do a long trip in them without a second thought.
I think the chatter, which we here a lot of, about them "hunting" is over stated from my own experience. I'm going Goodyear slicks, hand grooved, for the track, and getting a set of Bill Boards for my daily driver tires mounted on my second set of wheels. What to do with the GT-II's? I'll be sending up smoke signals with them when the Biil Boards get here.
Kirkhams say the Avons are the best going, I checked them out. EXPENSIVE!!! And they don't look that good, I'll pass.
Some GT-II reviews:

Like one reviewer said: "Wow. It's unreal how bad these tires are." Yup, I gotta agree with that.
