Most of the above info in not accurate. Ropes having different properties/elongations is not relevant if you are using half/double techniques. That is, clipping ropes separately. Different properties only matters if you are using twin techniques. That is, clipping both ropes to every piece. So, if you buy a new rope that is rated for half/double than get whatever you want. Never clip both ropes to a single piece of gear if they are not rated as twins. Half/double rope vs twin ropes are quite misunderstood. To confuse you more, recently some ropes are rated for twin and half/double techniques. In short, twin ropes must be clipped to every piece... and the ropes should have like properties. Half/double ropes should not be clipped to a single piece... and the ropes do not have to have like properties.
