I may be in the minority, but I am not a Brooks fan. Despite the fact that I am able to tolerate all of the saddles that came with my bikes, the B17 just didn't cut it for me. Most of the saddles I tried were okay at best when I started using them, but as I adjusted to them they got better and better. The Brooks was just okay when new but once fully broken in I didn't like it. I know that is the opposite of what others have found.
I didn't like the saddle that comes with the Fuji at first, but I used it for several weeks of riding around home and decided it was okay. I then rode the TransAmerica on it as well as some other tours and it was fine. I think it makes sense to give a saddle several hundred miles over a few weeks before abandoning it unless it is really terrible.
I'd still be fine riding across the US on that saddle, but if I were to pick a favorite saddle it would be one from the WTB Volt line.
Obviously YMMV, but I figured I'd share my experiences as just another data point.
