In reply to echo34:
> I am looking into purchasing a new rope for alpine mountaineering, and UK summer and winter scrambling. I am looking for it to be as light as possible, I was looking at the Mammut Serenity Superdry, probably in the 50m length (my current rope is a 35m 10mm, which seems to work well for two on the rope although a little short for some abseils).
If as light as possible is really the criteria, then this thread may be of interest:

> Would the Serenity work well for these uses? has anyone got any experience using it? I was also looking at the Beal Rando 30 for less technical routes. Would the Rando work for UK scrambling as well, or is it more specifically for glacier/walking purposes?
I've got a 30m rando I use for interesting walks and adventures where I may wish I had a rope if I didn't have one, which I guess is what scrambling is. Interesting thing about the rando is that beal rate it for 5 falls in a single strand 0.8FF 80kg configuration. It's quite a supple rope, coming from someone who mostly owns Mammut ropes.
You could recycle it yourself, I harvested all the ziplock buckles off my retired harness
