In reply to Sambo:

No. Because the concept of a durable and light wall rope is just nonsensical.
There are basically only two durable ropes for wall use on the market. They are the Mammut Gym rope and the Beal Wallmaster 6 both of which excel in what they are designed to do - at a price. In comparison, nothing else can remotely be described as durable and will get worn out relatively quickly.
As to a light trad rope, I'd recommend a Beal Booster III (9.7mm) as the most obvious choice due to its low impact force with a Mammut Infinity (9.5mm) or Beal Stinger III (9.4mm) as other good options depending if you want to go lighter.
