I ride a Brooks Flyer. I used it to replace a 45 year old original equipment B17 that was neglected by previous owners. I ride upright, so the wider Flyer with springs suits me. I also got the carved version. If I were riding with drop-bars, the B17 is fine. I also like the Berthoud saddles, especially the "natural" (unstained) leather, but they wouldn't suit my Pommy Dawes. I would use one or a Lamplugh if I ever had a bike on 650B's.
