I had to dump the saddle that came with my Cannondale almost immediately. I sorted through the box of old saddles at the LBS and found an old Selle San Marco for $30. Much better.
I think you're going to be a little sore after a century no matter what. I would think twice about dropping big bucks on a fancy saddle without having tried it, unless your LBS is cool with exchanges.
