Fixiegrrl (hope I spelled that right !),
just curious, any reason you're looking at the Aliante but not the Arione? It would seem to fit the general description of what you're looking for (medium hard, narrow nose, flat rear platform, etc).

I know, different strokes for different folks, but I have an Arione on my road bike and one on my cyclocross/commuter bike, and I'm loving it. Actually liking it more and more each time I ride it, doesn't give me pressure or chafing. The saddle on my road bike is new this year and it's a little early in the good-weather season here in the northeast so most of my rides haven't been super long yet, but I've taken it for up to 40 miles with no discomfort. Just my two cents...
