Help w/saddle decision

What is the width (outside edge to outside edge) of your sit bones?

I checked and assuming I measured correctly. When I sit and measure the sit bones it is approx. 4-4.25 inches. Now, what does that mean?

Means you got some tiny sit bones!

That's about 105 mm. Mine are about 180 mm.

Basically the centers of the "cheeks" of the seat should be the same width as the centers of the sit bones, or else you'll end up weightbearing on soft tissue and tendons or be concentrating weight too hard on the bones (if you are perched on the very edge of the seat or over the metal frame of a leather seat). At the very minimum, the seat needs to be as wide as your outside-edges measurement. My seat is 210mm wide. Most comfortable seat I've ever sat on.

With a 105 mm width, you've got a lot of choices of seats.

yeah, that sounds small even for a male pelvis. maybe you need to go to a shop with a "sit-o-meter" ?
I didn't like the B17 either. I rode one for about 6 months and well, it was better than the butterfly and the MTB and the seat that came with the tandem, but i was still getting like you said, a little bruising and discomfort on the longer rides.
that's when i went back to the B67 which I had BEFORE I got into serious biking.

Wow, your sit bones are narrow! Even more so than my husband's.
