One more question before you chuck the saddle out on e-bay -- is the pubic bone pressure more pronounced on one side, or is it the same on both? You need to know this, because if you are having more pain on one side, you are sitting crooked on the saddle. If you don't fix this before you get another saddle you'll just end up going through the same thing all over again.

If you have pain on both sides and are sitting squarely centered, then look to design issues. The saddle might be too narrow for you with your pubic bones ending up on the area where the saddle tapers in towards the nose. Or the anatomical dip might be too severe for you with the nose coming up & kicking you in the pubic bones.

The more you know about what went wrong with this one, the more likely you are to eliminate the same type of problem. No guarantees on eliminating other problems, but at least you won't have the same ones all the time!
