Just came across the Fizik Arione Donna. This is the one with a channel.* Has anyone tried it and if so, what do you think? I am currently riding a Terry SLX (flex); it is OK, but I'm always looking for the perfect saddle -- comfy, light and narrow enough to get behind the saddle when the situation calls for it.) The Fizik Web site does not list dimensions, so I can't tell how wide it is across the back.

*the Arone Donna 00 does not have a "relief" channel.
