You can tell if a saddle is going to be right by going into the LBS-Closing your eyes and say "I'll have that one" Probably will work better than any one else's suggestion for a saddle that work for their butt.
But certain saddles do seem to be popular. Selle Italia- Brooks-Fizic-Specialised. It's just that none of them are perfect for everyone.
