Martin, the problem is not the soft copper but that soft copper becomes 'hard copper' after some time. Due to bending, pressing and vibration the copper hardens and becomes brittle (much easier breakable then mild steel). Nevertheless it can be 'softened' again by heating it up to 'color changing' temperature. This should also be done on copper 'gasket' rings (oil drain plugs) before reinstalling. And Ed.. well if the lines are in fiberglass or firm mounted, so that no open swinging is possible, that's ok. It wont break until you try to bend it. But if you just coil it open around exhaust or make similar home made constructions, then the lines will swing and eventually break.
