My previous (defective?) saddle had the leather cover riveted out of axis. It exerted more pressure on the right side of my groin, my right sitbone was a bit lower than the left, etc. I kept riding it for a couple of years expecting the leather to eventually conform to my anatomy, but it didn't happen. My understanding being that once the saddle took its initial broken-in shape, it would not self correct over time.

At some point this summer, while touring, I got fed up wiggling to relieve my butt. I've tensioned the saddle, set it level (Brooks are often tilted upwards, more so in my case to relieve pressure) hoping to "reset" it. Three days later I was in pain (inflamed soft tissues). Contacted the dealer while the saddle was still under warranty, and tried to learn about alternatives (Brooks dominates touring such that I'd never bother to look elsewhere). Ordered two saddles and am now in the early phase of trying them out.
