Cormac, I have been using Shimano BR MC 70 cantilevers for several years. They use threadless post brake shoes that last me for years, I am primarily a tourist and many of my miles are on bikes weighing up to 80 lbs and I am confident in stopping. Easy to find on ebay, prices have ridsen in recent years though are still reasonably priced.
