How can you tell if "that" saddle will be comfortable? I am a fairly thin person, with little "padding" on my bum. I got a new road bike, a fairly high end bike, well... middle end bike, and the seat was SOOOO uncomfortable that I had to pull it off and replace it with a heavier more padded seat from my mountain bike. Is there a way to know if that saddle will hurt or be comfortable, without buying it and riding on it? Price? Does price dictate comfort? Any "tricks" you all can share?
