i find that the angle of the saddles that works best for me depends a lot on the riding position. i.e., the relationship between the height of the handlebar and the height of the seat. if i am bolt upright as i am on a raleigh 3-speed, i prefer to have the nose of the saddle angled up. if i am on a road bike and my hands are below the height of the seat, i prefer the nose of the saddle about level.
