The SLR-XP used to be my saddle of choice. I still have a couple, on my MTB and #2 bike, but my main road bike's got a Toupe now. It is more comfortable for my backside. Even though I measured at around 143mm on the Specialized butt-o-meter I am happier on a 130mm Toupe.

The Toupe does seem to be extra sensitive to angle. If you don't have a micro-adjusting seat post, chances are good that you'll hate it. But once the angle's right it is very nice.
