The Bates/Wintec/Collegiate Convertibles are all on the same two trees (flat seat and deeper seat.) They are too narrow for me. Many close contact saddles, especially the old original plain flap ones, have a narrow twist. They were meant for 2-point, not sitting.
Thornhill 24k and HDR Advantage and Pro have wider twists. Not sure about the Rivella and DeRivel or whatever the top-end is. The current Crosby Prix with the wider padded seat is also very comfortable for me. I liked the Stubben Edleweiss CS from a few years back, but the Artus didn't feel the same.
Most AP saddles have a moderate to wide twist. Dressage saddles vary.
