On the road bike, I'll probably switch from the 700x23 Schwalbe One slicks to a set of Vittoria Zaffiros I already have in the closet, or maybe an older style Rubino being discounted by various sites. Probably go with 700x25 for winter. Main problem with the Schwalbe Ones is skidding during hard braking, even on dry roads -- great tires otherwise.
Nothing different on the hybrids, they already have good all terrain/weather tires.
