In reply to damowilk:
A brooks saddle is simply a thick piece of hide suspended between the nose and the tail of the framework; like a leather walking boot it will stretch to fit the shape of your bottom. You'll notice that it has a stretcher bolt under the nose for taking out the slack. It is heavy and doesn't like wet conditions. Some people swear by them. I one tried a Brooks Swift, found it uncomfortable, crude and heavy so I sold it on.
Modern saddles are made from synthetic materials, so much lighter and they don't mind getting wet. They will hardly comply with your shape at all n the long term. A very popular saddle that most riders seem to like is a Charge Spoon and the slightly sportier version the Charge Knife, which I use and find comfortable for 100 mile rides. There's also the Charge Ladle, which is shorter and broader for women. Charge also have a brand called Fabric, which are also highly regarded. In the end it's a matter of what fits your shape best.
