I've finished reading this forum. Wonderful advice, some of which I can use:
• I'll try the "sitting on paper and scooting around" trick, to check my butt-bone measurements.
• I'll recheck my saddle position.
• I have a Specialized dealer locally who might help me with fitting, but their English and my Spanish are about on a par. (However, I'm taking classes.)

I'm hoping this LBS has a good return policy and will let me try different saddles, but it rather depends on whether we can understand each other in the first place.

Again, thanks in advance for advice and opinions on wide seats.
