It's a very personal thing saddles, what fits one wont fit another and fit is very important, personally I'd go to a specialized dealer and see which size you need.
Once I'd found that I'm best on a 143mm width saddle choice was less important, I have 2 x china carbon jobbies that are extremely comfortable for me due to being the correct width....they also weigh 100grams!
My more money, more padding recommendation would be a specialized romin pro evo carbon railed, I can't say enough good things about this saddle and if you get lucky like I did you might pick a brand new one up from ebay for £60.
