I've been very satisfied with my Panaracer Paselas in both dry and wet conditions. I have never once had a wet-pavement wipe-out with them. They are semi-slicks with an inverted tread, but I am extremely skeptical of the efficacy of this tread, for all the reasons cited by Raiyn and others. I'd like to try the Avocet Carbon 12 FasGrip slicks, but alas, I do not have a bike that can roll them right now. I am hoping to get a new bike this summer, though, which will give me the opportunity to try out a slick tire. It's too bad that they're so hard to find, as I really don't think that tread makes any difference on the kinds of surfaces that I usually ride on.
