I'm about to try out an Arione Donna (arrives at LBS today eeeee!) and it has a nice central channel down the whole thing and is 145 mm wide. My old saddle was stock on a WSD bike (I figured it was good for me, doh!) but only 130 mm at its widest, but it did have a little dipsy do in the middle. Turns out I've been sitting on my tailbone and soft tissues for four years. When I upgraded to the men's Arione (thinking it was the right width for me) and it was awful, lbs measured my sitbones at 140 mm. This should be good. Hopefully my saddle search will end here... but I'll have to keep kermit's saddle in mind!
