There are some saddle out there where some nose down is good for me it's Prologo but it's a couple of degrees, Flite's I like nice and flat, and Brooks a bit nose up. I think if the company builds a little extra in the nose assuming your going to move forward on the saddle then it needs a bit of tilt. I'm a bit different since I'm built more like an ape than a human with my short legs and long torso and arms.

I still think odd saddle angles are a result of the "buy a smaller bike since you can make it bigger" trend that seems to be pervasive on the internet.
