Unfortunately I have nowhere to try the saddles since none are available for purchase I am going to order from Chain Reaction Cycles probably,so I am very limited... The only thing up for sale near was Selle Italia Lady TransAm‏ but I don't know anything about it.
The Selle SMP TRK looks ok, I have actually been thinking about that one, Fizik Vitesse and some of Selle Italia(Lady,Diva,Lady SLK & SLR)...
Also can you tell me the difference between Fizik Vitesse Sport, HP and Tri? I mean in riding them?
