I just ordered the SMP (ladies version) and a Selle SLK Lady Gelflow. I really like the Selle Italia Lady Gelflow saddles that I have on my Dolces. However, the saddles on my other two bikes aren't comfortable enough for long rides---one has a Terry Butterfly Ti and the other is the Bianchi that came w/the bike.

By the way, how long do you reckon is the average lifespan of a saddle?
