Having read many a saddle thread, I believe that the only saddles that are widely accepted as comfortable are Brooks. I know that's not the answer you want, but that's what I have seen here. You may need to try a lot of other saddles before you find one that fits you well enough to be acceptable. 'There's a butt made for every saddle,' is a true saying. I think you are going to have to go by trial and error.

May I suggest you spend time visiting thrift stores in search of bikes with old saddles. I got an old Raleigh (1980 vintage) that has an Avocet Condor saddle. It's a vinyl saddle but is much more comfortable than most non-Brooks saddles I have used. I think that modern saddle manufacturers have fallen into the trap of making saddles that are either extremely light weight, or that complement the sleek look of the bike. An older saddle might work for you.
