There is so much saddle information out there that I am having a hard time getting caught up to speed on all of the different brands and models. Could anyone suggest where to start in looking for a saddle?

This is for a road bike that will be for commuting to/from work at the outset, sitting in a not-very-aggressive position.

I am not sure that I am measuring accurately, but I am pretty sure that my sit bones are spaced wider than average, like around 145 mm, or thereabouts, maybe? Is that big? I have a smallish frame, but I did birth a giant baby (11.5 lbs!) without too much trouble, so I suspect I have roomy bones down there. (Not TMI, I hope?)

What's a good saddle to try? I'm not looking for super fancy at this point, just something serviceable that will fit until I figure out what I like.

Thanks!
Gillian
