Brooks has treated me the best so far, but I keep an open mind about it. Would like to try a Specialized Toupe next.

Have:
B17 on fixed-gear. The flattish top agrees with me for most riding, but is a little too wide in the rear -- it's not a huge problem because I am out of the saddle often enough. The top is the flexiest of all my Brooks saddles, but I don't mind the extra give on this bike as I don't always have the opportunity to lift myself out of the saddle for bumpy roads.
B17N on go-fast road bike. Width, top shape, and hardness are all about perfect.
B5N on rando bike. Much like the B17N except a little flexier. Nice for brevets.

Gone or no longer used:
B17S: My first Brooks saddle, ridden for a couple thousand miles. Nice flat hard top shape, but too wide. Hanging on to it in case I want to use it on more of an upright bike (or someone offers me money for it. )
Pro: Just couldn't make the rounded top shape work with my anatomy. No amount of adjustment or riding light could make it disappear under me, so I sold it after about 1000 miles.
