+1 on the Rivet Pearl with cutout Nick!
I met and talked to Deb (the Rivetress) at the Philly Bike Expo last year and chose a Diablo for my new bike that was under way. The width looked precisely what I needed after review of my B-17 and its sit bone impressions. I rode it for four months including two century rides, determining that I needed a bit longer fore and aft area of consistent width adequate for my sit bone spacing as I move while pedaling in a seated position on varying terrain. The Diabolo cantle shape limited that to the rear for me and adjustment of seat rail position win the seat post clamp compensated for more forward movement but took me where the saddle narrowed to less than sit bone width. Had I picked Berthoud or Brooks, I too would have an extra hundred dollar saddle I liked 80% on my shelf.
Rivet has a great warranty where if within 364 days it isn't right, they'll help you figure out the next move and trade you. The others don't do that and it was great it was to have that ability. You can't be too sure you don't pick a saddle with discrete bias or overzealous objectivity and Deb knows that as a long time rando and multiple P-B-P rider.
