Lance Armstrong had a response to someone who asked about those 'tiny little saddles' in one of his books. He told them that when you are on a bike for 6 or 7 hours, the smaller the saddle the less places there are to rub.

That made sense to me and it helped me get past my 'cushy is better' misconception back in the early days of my cycling career. Of course, the experienced women at TE helped too!
