Test saddle programs > everything else.

Unless:

1. you want to spend money buying-selling what didn't work for you
2. you just have tons of fellow cyclist-friends who will be nice enough to lend you his saddle for week/s

Numbers (widths, sit bones, etc) are only a part of the "mystery". You really have to TRY and use a saddle to figure out what works for you and your "boys". Testing a saddle @ the shop doesn't make any sense. That's only a brief period of time and you need to put on hours to figure out what's best for you.
