Why? What?

Why not just start with a comfortable (for you) traditional bike saddle? Those contraptions you linked are heavy, over designed to replicate early suspension saddles, made with inferior leather, and are of suspect quality. Again, why? A commuter saddle has to stand up to the rigors of daily use in a wide range of conditions. Try something durable, but start at a bike shop, not on eBay...

What saddles have you ridden so far? What characteristics worked for you, and what didn't? How long is the commute?
