When I bought the 2011 S-Works Tarmac last Aug they came with GP4sII, I have 1,652 on them, dunno how many miles before, and they look good-to-go thru the summer. Put 25C GP4sII on the Roubaix, seriously improved the ride.
After those 2 flats on the Verdi ride Sat I put GP4sII on the Lil' Tarmac (replacing Conti Ultra-Sport). Much less rolling resistance, better protection and grip. Found a set (new) on eBay for $35ea. Now I have 3 bikes with GP4sII tires.
