A B68 Brooks? What about it didn't you like?
Being of the big pelvis variety and being vegetarian I tried very hard to find a wide saddle besides the leather Brooks. In the end, I bought the Brooks. All of my bikes are outfitted with a B68 with a cut-out (added by Selle-Anatomica).
I rode a Selle SMP Lady Strike for quite a while. It was almost wide enough, but the Strike variations are heavily padded. They were only good for about 50-60 miles and then foam fatigue set in.
The Terry Rosie is wider and REI sells a Respiro saddle that is really wide. Needless to say I wasn't impressed with either.
The problem in the market is that saddle manufacturers think wide means fluffy. You can find wide saddles, but to find a wide saddle without thick padding....
