That seat looks very good and comfortable. The leather looks awesome and while it will require more maintenance, @ChrisPDX is the perfect person to tend to it. Me, on the other hand, would have it rotting in a week.
Chris has mentioned to me that he'd like to take the bike touring. As he road races now (and has for a very long time) he doesn't the urge to drag pegs on the street. That's only for posers who don't actually race.
