I'm the other person getting great pad life out of my BB7 pads on a heavily loaded touring bike riding in often mountainous areas, but I'm not a brake dragger and am comfortable at speed and judging when to control speed.
my actual proof--photos of my front pads after about 6000km of nearly all touring kilometers, so 4000 miles for you Imperialists.
and the link to the thread I put up to give some reference to folks wondering about pad life, but emphasizing my riding style and the importance of how one uses ones brakes that makes ALL the difference.
Quite literally, your mileage will vary.
