I found a B-72 at a bike shop and picked it up for $40 with a seatpost. It was dirty from sitting under the counter for a couple of years, the owner had traded something for it.I thought it was used. I took it home, wiped it off and found it to be new and had never been mounted to anything. I treated it and mounted it. It was comfortable from the moment I installed it.

My B-17 mounted on my LHT is a Special model with the brass rivets in honey. It has thicker leather than the B-72 and it was mildly uncomfortable on 35+ mile rides as it was breaking in. Now, 800+ miles later, it simply disappears underneath me. I had to get an infinitely adjustable seatpost to get the angle just right but now it is seat nirvana. 50+ mile days feel fine. I get off and it doesn't feel like I have been riding and can get back on an go. The saddle breathes and the original slickness goes away soon.

If you are having issues with the nether regions, it is a fit issue or your shorts. I had some problems and found it was the padding in the shorts that caused the problems. I was wearing a pair of Endura mountain bike shorts and the pad just didn't work. I bought a pair of Bontranger shorts and they feel great. Usually though I just wear shorts without the pad and it feels fine. No other saddle lets me ride so far without padded shorts without discomfort.
