I love the Terry Butterfly with Ti rails. I don't think I will ever use a different saddle. Not sure if you would want a saddle marketed to women, though. I bought my saddle used and three years later (riding 3-6x week), it is still in great shape.

Last year, I did have a period where there were creaky noises coming from the saddle. I turned the bike upside down and put some oil over the area where the rails connect with the saddle and let it sit. I had to do this a few times over the course of a few weeks and I haven't had any creaking noise since then. I still oil it once every few months. I don't let my bike sit outside in the rain and I don't ride it in the rain much either (not much rain where I live anyway...).
