I suspect the entry-level Brooks aren't done by hands, as little as possible to control cost. The larger hand-hammered rivets should provide superior shear strength if done correctly. That said, if you don't soak the cheaper saddle in water and ride, then it should be good for at least 20K miles. Don't forget to add a little oil to the saddle once a year to keep it from drying out. I use the stuff found at sporting goods...baseball glove conditioner sold in a white container that resemble a box of Kiwi shoes polish. Looks like yellow hair gel!
