My saddles are all a little nose down. Actual setting comes after riding with the wrenches and tweaking until it disappears. For me, no plastic saddle has never achieved "disappearing" set level. (Leather saddles are for me a near torture when I pull forward onto the hard leather on steel nose. And as an ex-racer who loved and still does using the entire saddle, that simply does not work.
Went for a 44 mile ride yesterday on an early '80s race bike with a hard Specialized race saddle aimed slightly down. This post is the first time I thought about the saddle at all.
