I had the Phenom but found it way to flexible. Some may prefer this but after 50 miles my ass would hate me. I have an Arione now that I love but it may not work for you - it is super stiff.

I know my LBS has the Specialized and Fizik saddles for test rides and there's a shop in Pasadena that has the Selle Italia saddles as well. I would look around that area and find dealers for these and give a few a try for a week.
