So now that you've read them you should be drinking the kool-aid that slick tires are the way to go because they maximize grip on pavement and will never hydroplane.
I don't think so. The truth is, grip on smooth pavement will never be a problem with bike tires. As Sheldon's chart shows, it's basically impossible for you to ride fast enough or corner hard enough to exceed the friction limit of a bike tire on pavement - even wet pavement. So why optimize for that? Slicks might give you optimum grip, but you already have plenty.
In reality, grip issues when biking will occur when your tires *aren't* in contact with pavement. I've had bad wipeouts due to gravel, sand, etc. In Seattle we also have the "steed" - the rotting leave gunk that's as slippery as a banana peel. When your tires are on steed you have no grip, and a bit of a knob to cut through that and get to actual pavement would be a huge boon. (it's called "steed" because rotting leaves are almost the most disgusting thing in the world, they're goopy and brown and smelly like a giant film of shit that gets on everything - second only to Paul Steed who is the most disgusting thing in the world).
I don't know what the best compromise is for a tire that can cut through some steed but still have good pavement grip. Clearly if all you care about is wet pavement grip, the right thing is a slick tire that's as wide as you can fit, and underinflate it very slightly.
