First saddle I tried was a Selle Italia Lady Gel Flow (which I have been told is essentially the same as the Terry Butterfly...?). Miserable. Too wide and too pear-shaped for me. The cut-out ended up too far back, since I would end up too far forward on the seat because the shape was so wrong for me.
I now have a Specialized BG Jett 143...perfect. I love that saddle. T-shaped and narrower was what my rear-end needed.
