Every point of protection that is passed must have both straps cut because the strength of the rope is less than half the rope.
The elasticity of this thinner rope also means that a climber falls a lot further before being stopped and although he will suffer a much lower collision force, the extra distance significantly increases the risk of injury by hitting something when you fall.
Used as a pair, the rope offers protection as much as one thicker rope in autumn situations and provides the advantage of being able to follow the full length of the rope rather than the part.

But they have the same drawbacks of rope drag when lines run from side to side; coupled by the fail factor must clip two straps into protection.
The last category of climbing rope is a simple hill walking safety rope that is intended as collateral for group members walking or scrambling but not as a leading rope.
These are usually around 8mm in diameter and are a type of rope that the leader can use to secure his group members when they handle steep droplets and even when down simple but steep grassy slopes. These types are clearly marked as not suitable for climbing and climbing.
There are some very critical points here. Twins really should NOT be used as a half or single, just because of extensions when they are loaded – they are stretchy little blighter! Although every half rope is given a value for falling alone, it is a bad practice to use it as a single, because they are far less resilient than a single rope rated full.
