Long time brooks user here (over the years i have had experience with 3 flyers, b67, b17). Brooks saddles are very simple in their construction and that is the appeal for me. They cost a lot but one can find them on discounts on a regular basis. I checked the Berthoud and it seems like they are going for the more posh/hipster looking leather saddle. They look fine, would love to try one out. from the pictures they don't look that comfortable though looks can be deceiving...
