I found a leather saddle is the only thing that works for me, there are no saddles that are curved from front to back, firm, and narrow for sub 110mm apart sit-bones. Leather accommodates you no matter what your personal physiology. I too thought I was going to have to quit after the last "saddle sore" turned out to be a PNI (basically a knot of scar tissue from repeated irritation) which required surgery and 7 months off the bike. I tried a Selle Anatomica as a last act of desperation and have been happy ever since.
