Thanks everyone for your insight, it was very helpful.

I am in the transition from doing lots of scrambling to attempting some alpine routes that require some protection, i.e. some glacier travel and some exposed slabs in the Olympics. I like to go lightweight and was wondering if 60m 8.2mm rope, like the Petzl Dragonfly rope would do the job. Can it be used as a single rope as mild protection and during glacier travel? Or must it be doubled up?
