OK, I did 20.7 miles on the SMP today. The final tweaking yesterday worked - I think I'm in love. No perineal pressure, no manly bit numbness. Some sits-bone pain, but way less than I'd been having and it might still be residual from the stock saddle, my butt has been pretty consistently sore. I feel great, and normally after my Sunday ride my tuchas hurts enough that I've been taking Monday off. Not this week!!!!!
