What frameset would have a feel somewhere between the raw, taint punishing aggression of my Fuji and the springy, loafy ride of my Cross Check?

I love the handling and acceleration of the Fuji, but it really pounds my legs and bum. My Cross Check, by comparison, has a very smooth ride, but it feels like I'm pedaling through mud. :-/

I ride mostly around town, which means a lot of stop-and-go. Bonus points if I can put fenders on it.
