I ordered a Brooks B-17 Titanium Honey for a CF road bike (pic here: http://www.bikeforums.net/showthread.php?t=369834)

If you don't mind steel rails, I can recommend the pre-aged (preconditioned) Brooks B-17--it costs a little more but it gives you the equivalent of one-year of aging. I need a wider saddle but if you want a "racing" saddle (for more agressive riding), you may be considering the narrower models, e.g., Brook's "Swift" and "Team" saddles.
