When I went through a bike fit session years ago, I must have tried at least 20 different saddles: some for only a couple of minutes when I could tell quickly they weren't for me, and others for a couple of weeks that were possibilities. I found the bike fit session very beneficial - not only is it about saddle selection, but about general cockpit positioning that will have an effect saddle shape, positioning, tilt, etc. If you haven't been through one, perhaps you might find a fit session beneficial as well.

FWIW: I've since become a fan of BiSaddles, which allow for both fore and aft inward/outward adjustability as well as being able to tweak lateral support. Because of their adjustability, they take a lot of "trying" out of the process.

Good luck with your search.
