Easily done. Just ride 'em. A far better means of choosing something that you are going to become very intimate with than any formula or test.

Any good shop should let you ride the saddle you purchased and bring it back for exchange or store credit if it doesn't work out. (No, not all shops are doing this yet, but the numbers are growing. Portland has a shop that takes this to a new level. They have a saddle "library"; literally. Shelves of about 2 dozen saddles. $25 gets you a library card and you can take out a saddle, ride it for two weeks, return it and take out another. Find one you like and they will give you a new boxed on and credit your card money toward it. (Gladys Bikes.)

Sit bones are not the only issue for comfortable saddles that work. We are all as different down there as our faces are different. (No, I haven't looked. But I have been observing the saddles people find comfortable for the past 50 years. Wow! are they different. The Brookes seat that are raved about by many are a** torturers for me. I had a high quality Brookes copy on my commuter years ago. When that bike got stolen it was sad except that I got to ride my favorite Selle Italias again. Hallelujah! A few years later I stared to see my body change, Those seats no longer worked. Now it is seats that are not all that different from the Selle Italias - and I believe made by them - but with the cutout, Terry Flys.)
