I think about the carnage that would happen in a bike race during pack crash with disc brakes and I shudder. Those things are sharp. Until there are some regulations about rounding the edges of disc rotors properly, I don't think UCI will legalize them.
I think tourers like to be as simple as possible. With cantilever brakes, you can find replacement pads at any Wal-Mart. But then again ... disc brake pads last a LONG TIME and they're small enough to pack so ... It took me 2 years to wear out a stock pair of Avid BB7 brake pads. I know they have definitely made a dent in tandems where there vastly superior heat dissapation makes them clearly superior.
