Just one more data point...
I found the one Brooks that I owned just OK when new and progressively worse as it broke in. So yeah they are not for everyone. Also I would consider the fact that they are much heavier than most saddles so they would have to be much more comfortable to be worth the weight penalty.

I guess I am lucky in that after a few hundred miles I adjusted to all of the original saddles that came with my bikes and I would happily use any of them if I was doing another TA. I always advise putting in 300-500 miles on the saddle that came with your bike, before considering a change. I have always done that and even the saddle that I thought was awful on the first ride worked out well (I used that one on the TA). It probably helps that I ride with lower than average bars so I don't have much weight on the saddle.
