Another 28c, 4 Season Grand Prix rider, on a cross bike set up for road / touring use. I like the tires, so far they're pretty robust.
Oddly enough I haven't noticed a big difference between 25's and 28's, or between 23 and 25 on my road bike, at least as long as the PSI's are the same. Big difference when I use the 32c 85psi cross tires that came stock with the bike -- kind of mushy and bouncy IMO. Should be fine for winter use.
