Personally find the seat tube angle of 72 or less is better with a Brooks. It doesn't make any sense to adopt the standard 73 degree angle if the bike doesn't need an offset seat post, and the main saddle choice has minimal rail adjustment. All assuming one is trying to preserve the cockpit position that one typically uses on a 73 degree road bike. So in other words if it's 73, they missed an opportunity, but it will obviously be fine, and if they go to 72, it will just be that much better.
