I just can't believe that you didn't chuck a saddle that isn't right at 500m or a 1000m, Tony. And for sure, at 2500m, if it hasn't cuddled up to you and licked your nose, you're never going bond with it. You've given the legend a fair go, so sell it on, get something you can sit on and forget about forever.
To anyone contemplating a Brooks who haven't had one before, it's been said a couple of times already in this thread, but it is important enough to say again: you don't choose a Brooks saddle by the model your pals like, you chose one that is wide enough for your own, individual, personal sit-bones and, furthermore, the more upright you sit, the wider your saddle has to be.
