I too started off with good ol' Flites. There just wasn't much else to choose from!

I tried a Vitesse (womens saddle from Fizik) when a rep recommended one and still use them on the road.

I use the Titec Berserkr ("mens" saddle) on the mtb. It's not so much the width as the length (ohhh that sounds bad! ).

It seems that saddle comfort is more based on sit-bone spacing than perceived "size". In other words there are plenty of women who are not a size 4 who still have narrowly-spaced sit-bones and should try a few "mens" (narrow) saddles.
