Deluxe model, copper-plated rails, large copper rivets.
The Professional series is most appropriate for vigorous cyclists who set their handlebars somewhat lower than their saddles. The leather is a bit thicker than other models, making the professional a little slower to break in, but making it the most durable model.
i've ridden enough synthetic saddles, and had enough tired butt to seek out a cure. now i, too, am a believer in the minimalism of the brooks leather saddle. the only downside, if it can called such, is the need to cover the saddle during rain (i use a plastic grocery bag); then again, if you're in rain on a bike, you'll have other things on your mind--and none of those things will include a sore butt.
