+ 1 on the lack of love for the Brooks line.

For me whatever came on each of my bikes has worked out OK. I'd take any of them on a multi-month tour. The one Brooks I tried was just OK when new and went downhill from there for me. By the time it was "fully broken in" I hated it.

When I did buy a saddle for a used bike that came without a saddle I bought a Prologo racing saddle. I forget the model, Kappa maybe? Anyway I really like that saddle pretty well, but I like the o.e.m. saddles on my other bikes well enough too.

Anyway my suggestion is to use the saddle that came with the bike, adding miles slowly as you break in to the saddle. Replace it only if you find it unacceptable after a break in period of at least several hundred miles spaced out over a few weeks. I have logged many thousands of miles on a saddle that seemed awful when I first tried it. After a few weeks I started to like it and soon after took it on the Trans America for 73 consecutive days of touring. Since then I have happily done a bunch of other longish tours on it. FWIW that was the saddle that came with my Windsor Touring (same as the Fuji Touring).
