Like Panthers007 stated each person is different. For the length of ride you stated I like the Brooks. I have the Brooks Flyer on my touring/commuting bike. The most common Brooks though seems to be the B17. They are usually heavier than the plastic and foam saddles but are rather comfortable. I also like some of the Body Geometry Saddles by Specialized. You may also want to get fitted by a Specialized dealer.

However before going out and buying a saddle I suggest first checking the saddle height, tilt, and fore/aft position.
