I haven't tried the Zero but I'm currently testing out my new Falcon X. So far I'm very happy with it. I rode the Falcon on a 72 mile ride this weekend and was pleased. I did have a bit of pain towards the end of the ride, but this was concentrated in the sit bones and not at all where the cutout was-no pressure there at all. The seat is not super padded but I prefer a bit of a harder saddle. It seemed to be the perfect width, supported my sit bones but with no chafing on the sides. The cutout was the right size. I think I might have found the perfect saddle, but want to ride a bit more before I'm fully committed.
