Sundial...great questions you ask! Yes, I'm using the original stock seat. I bought this bike in 2008 and it was an 'o7 leftover.

You nailed the spot...right in the crease. I even checked to make sure the seams of the bike shorts (where the padding connects to the shorts) wasn't causing it. It's not.

And the saddle, I never would have thought to go narrower. I'm "J-Lo-esque" as my DH likes to say. About a size 10 with 40" hips. I would have never thought to go smaller.
