I second what has previously been posted. Ride as many bikes as you can to figure out which works best for you in your financial frame. I ride a Trek 7000 and am very content with it even though an upgrade would be even nicer. If the saddle is too wide, it may cause problems later down the road which make cause you to be off for some time. Find both a bike and a saddle that are to your liking and enjoy the ride.
