I didn't have any sit bone pain w/my Ruby, just the area where the muscles meet the bones.

I finally found my list of saddles I've tried...
The ones I mentioned in the last post didn't cause any of that type of pain, but the WTB Speed She actually caused severe pain in that area for me. I guess it's the arrowhead shape or something, because I remember actually limping after a long ride on it and having to take a few days off afterwards.
