I got a Specialized Allez Sport this past summer and really enjoy it. the stem is flipped so the riding position is quite comfortable BUT i'm already lusting after a Roubaix. The roads here are rough also and i think the Roubaix with its carbon frame and zertz inserts would be a great ride, it's also light and the riding position is quite comfortable, i'll be auditioning one in the Spring. You could check
www.specialized.com for photos and to see if it comes in a WSD.
