In reply to AdCo82:
I've been using a pair of them for everything for well over 10 years now (not the same pair!). Very happy with them, handle well etc but like all ropes, the dry treatment does wear off. I tried reproofing one once with some Nikwax stuff. It did work but didn't last as long as the original treatment.
I've considered dropping to 8mm's to save weight but they just feel too skinny. Too slick in belay plates and too thin when there are sharp edges about. I know others wouldn't worry about these things but you have to feel confidence in your ropes.
