Several years ago, I felt my trusty Butterfly was too wide and tried a Damselfly. Big mistake! Not only was it *much* narrower, it was *much* harder (all I could think of was riding on a two by four), and the cutout was so narrow it pinched my girly bits and left me raw. I had to sell it.
I do know that some gals really like the Damselfly, but I found it surpremely uncomfortable. There are plenty of slightly narrower saddles now that look much nicer to me -- like the 143mm width Specialized (Lithia, Ruby, Jett, and others).
YMMV -- just wanted to put my two cents in.
Emily, happily riding her Butterfly again
