I have replaced my Brooks B17s with Fizik Vitesse saddles. They are much lighter and more comfortable for me. The Vitesse is marketed as a women's saddle in the US but unisex in Europe. It is shaped just like an Aliante but wider, which is one thing that makes Brooks more comfortable for many people. However, if you have a saddle that is comfortable for you on your other bikes, there is no reason why it wouldn't be comfortable for touring. I've got the same saddle on all of my bikes -- racing, touring, commuting.
