In reply to lisa:
ive got an 80m one. I think its great, used it in Kalymnos for exactly the kind of climbing you described.
Its very light, nice to handle and doesnt stretch too much for a thin rope.
Its fine with a grigri 2.
Hard to know yet but it probably will wear faster than thicker ropes but thats probably to be expected.
I would definitely use a thicker work horse rope for working routes though
