How did you choose your saddle?
I've been using a borrowed mountain bike with a large, wide gel seat. When I first sat on it, I was amazed at how much more comfortable it seemed than the seats on the bikes at the gym.
Several months in, I'm not sure all that cushioning is a good thing. I've had some TMI problems with my back end that got me prescribed some very nice (read: painful) steroid cream. I can't help but think that sitting on a harder surface that had more support might have helped prevent that.
I understand trying saddles out before you buy them, but how do you know what will work well over time? I can't imagine anyone sits down on a Brooks saddle and thinks it's comfortable but people buy them all the time.
So - how did you pick YOUR saddle?
