I was just thinking. Maybe you are expecting too much from the saddle?
Most people that ride really long distances no matter what saddle they are on end up with sore and tortured butts. 200 miles is a rather long ride.

I don't know anyone that did it that didn't have sore sitbones, or chafing or something like that. I read a bunch of ride reports from the PBP (Paris Brest Paris 1200 k ride) and SORE BUTTS is the #1 complaint, well, and lack of sleep.

how are you after a 50 mile ride?
