FWIW, I've been using Fizik Vitesse saddles on all of my bikes for a while. It is shaped like the C17 or a broken-in B17 and about the same width as the C17. I was using B17s on my main bikes when I picked up my first Vitesse in a trade. I liked it so much that I've since put them on all of my bikes. The Vitesse weighs considerably less than a C17 or B17. I have bought most of my Vitesse saddles on eBay for much less than $30. I've bought at least a couple of them for less than $10 and the most I've paid is about $35. The saddles I've bought have ranged from take-offs that were essentially new to used ones with light wear. Mine are all the titanium rail version, which weighs about 250 grams.

I've been tempted to buy a C17 just to try it out, but can't get past the price. I think it would fit me because the shape and size is similar to my Vitesse saddles as well as my broken-in B17. I saw a C17 for sale on the local Craigslist once for $60 and immediately emailed the seller telling him I would take it, but somebody beat me to it.
