What she said - there is very little (if any) correlation between the distance between her sit bones and the amount of padding she carries on each side
And a comfortable saddle is all about supporting the sit bones well. Too narrow saddles are hellish to ride on.
Saddles are very individual, but if you browse around the forum a bit you'll see not only a section devoted to discussing saddles, but also that many of us have information on which bicycles we ride and which saddles are on them, displayed in our signatures. That should give you an idea of which saddles are fairly popular. Specialized I know offers the same models of saddle in 3 different widths, so if you have a Specialized dealer nearby that might be good place to start.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
