I've enjoyed many a B17 Champion Special, and a few not, and only a few B17 standards.
NOTE: I'm six foot tall, 165lbs, with a 13cm sit bone width. I run a few times a week and do a couple of 25 mile rides each week, and shorter rides for errands, etc. Long way of saying I'm not real wide and there's not much mass on me.
I've also got an Ideale Daniel Rebour in my stash, which is said to have superior water resistance. Never tried the water resistance, though. It is also very nice.
I never had good luck with the Berthouds. Like sitting on granite. Hard hard hard. No break-in. Tried three different ones. Gave up. Ditto for the Brooks C67 (the Cambium version of the B68). The C67 also had a very wide nose, which did not work for me - I guess I've got developed adductors or something.
I recently bought an LHT and have a more Albatross/Tosco-type upright position on the bike. I tried a bunch of Brooks and Specialized and Ergon saddles, all 155+mm width.
There is one that I settled on, that is really fantastic for me: The Ergon Mountain SMC in a women's medium/large. I think it's about 160mm at its widest, and weighs 300g, so maybe a half pound lighter than a B17, and to me, just as nice. It was about $70. There's a picture on the Rivbike site with what I think is the same saddle on Roman's Sequoia:
A note about saddle width: leather saddles have those beautiful rivets. The rivets, for me, reduce the functional width of a saddle. Here's a photo of a 155mm saddle mated to a 220mm wide saddle. Their 65mm difference is minimized by the rivets, and their functional width is similar:
Both those saddles (Brooks B68 and Ergon SR3-L) are available for purchase if anyone's interested!
