In reply to paul:
thinner ropes do wear out faster, if you're going to be using it a lot look for an 11mm one, having said that i have a 10mm Roca rope, which acually has better fall stats than many thicker ropes, with 10 factor 1.78 falls.
There's no reason why it shouldnt be suitable for outdoor use, except dry treatment is preferable for wet weather or ice climbing, and ive heard it makes th rope more durable too
