OP, please do let us know if at the end of this thread, which will no doubt reach many pages in length, you are any more edified on the matter than when you first posited the question. I mean, feeling yourself out in the shower is all well and good as far as it goes, but you still have to procure a saddle that you find that you and your posterior can live with. Saddle Nirvana is out there, I can assure you. Out there; not in here.
