Every time this question comes up the same answers are given. Some like one saddle some like another. What works for you may not work for your wife. Some saddle advocates are more vocal that others but the one piece of advice that is
golden is try before you buy or expect to have a shelf full of saddles. Metric man has a collection and had I not sold off some of mine I would be in the same shape. The second thing is be sure you are used to riding and that you have your bike set up correctly before you assume the whole problem is the saddle.
There are no magic saddles that fit every bottom.
