I like the old school Selle Italia Turbo saddle for almost everything ---- the rounded profile is nice compared to the angular shells on a lot of modern saddles --- But that said, I also tried a Specialized Power saddle on one of my road bikes on the advise of my LBS's staff --- its great - If I had the budget, id have several of these

But saddle choice being highly individual, id try to visit a Specialized dealer if any are in your area and see if you can demo a saddle or two
