I have both and find they are as ok as saddles get for an upright bike. The Selle is great for a while, but starts to flare out and cause chafing. The Rivet doesn't cause the chafing, but the hardness is a little too much (for me) for anything over 50 miles. The recumbent bike has been my best solution. As for the cutout, I think it is actually a little better on the Rivet; the soft bits don't "extrude" through the slot quite as much as with the Selle.
