After 10 years of wrestling with this question-and using 6 different saddles-my LBS had an ingenious solution in addition to the assurance that the saddles were returnable. We placed an assortment flat on a bench and I sat on 'em. I eliminated one after the other until only one was left. No more sores. No more discomfort. I have 1K+ miles on the new one. Simple and may not work for everyone. Worked for me.
