Thank You, Everyone!
I am overwhelmed by your helpful replies! I clearly have a number of useful options to pursue.
In answer to the reply with further questions for me: I am 165 lbs. and 5'11''. My route varies, but I don't think most of my rides are particularly bone-jarring. I looked up the Terry saddle site, and then showed it to my wife. She doesn't ride as long or as intensely as I do, but she also complains, and some of their saddles seem especially female-friendly.
I remember the old Brooks Professional from decades ago. I am pleasantly surprised to hear they are still in business. I've been reading bikeforums.net for awhile, but I am still clearly behind the curve on bike products available out there.
Thanks again, everyone.
