Right after I posted this, I noticed that Schwalbe says that Fat Franks are identical to Big Apples, except for the tread. They also come in black, so they'll looks less goofy. The RiBMo's that exile mentioned earlier look expecially promising (except for the logo on the sidewall...). The reviews on them are pretty excellent. I might consult my LBS later, to see what they recommend for slicks.
