Another vote for the Fizik Vitesse. It is shaped like the Aliante except wider. The titanium rail version only weighs about 250 grams. I was using Brooks B17s on my bikes until I tried a Vitesse, which I found just as comfortable (or more) at less than half the weight. I have since put Vitesse saddles on all of my bikes. BTW, you can often buy Vitesse saddles on eBay for bargain prices, either used ones or take-offs from new bikes. I have never paid full price and have bought them on eBay for prices ranging from $10-25.
