Ok Rich, time for you to be a bit more specific of your intended uses.

If you're talking about using autocross tires just for autocrossing, then the Hoosiers will do as well if not better than the Kumhos, regardless of them being 15" versus 17". You commented about them being a little "exciting" on the street. Are you going to run them on the street? Because your last post now mentions using big letters on the street. If you're not going to running the Hoosiers on the street, why do you care if they hunt? If you're properly set up for autocross, you're going to have so much toe-out that the tires will be the least of your worries for "hunting". Tire Rack will shave and heat cycle them for you. I normally get mine shaved, but cylce them in by driving them to the track. I've tried all manner of autocross tires over the past 20 years...on everything from a 92 Vette, to heavy Audis to Cobras. Yokohamas are not called Rockahamas for nothing, but will wear through two seasons if you want, Goodriches are excellent but expensive and would rarely take me through a season, Kumhos are damn good...but one brand remains constant in providing damn good stick through its life, reasonable wear and reasonable cost, not to mention 15" sizes to fit a Cobra...Hoosier. For it's limited use in autocrossing, 245s up front, and 275s behind do quite well.

I ran TDs on my Butler as a single tire for autocross and street duty for three years. I would set the toe back at the event's end and drive back the 60 miles to home. Yes, they hunted and picked up gravel...BFD. Just keep both hands on the wheel.

I run big letters on the Kirkham. They are not going to be legal for any street class (ie., street prepared) at an SCCA autocross...non-DOT. Also, they're not going to warm up fast enough, nor do they have as stiff a sidewall as one would like for autocross. For that, the TDs are better, and they are legal for classes typically run.

I gave my advice based on you running tires specifically for the autocross. TDs can be used on the street, but there are compromises to make.
