I use 700c X 25mm up front (Criterium) and 700c X 28mm in the rear (Parigi-Roubaix).
Type of Riding - clean, smooth asphalt roads
Speed - slower than I use to be :-)
Price - ride quality is more important, hence, the Challenge tires ($60-$70 each)
Preferences - light, lively, tubular-like ride quality with the convenience of a clincher.
