In reply to PaulW:

Pity they don't last though. A couple of friends have them and both ropes are looking pretty knackered after not very much climbing.
To the OP:
My Stirling Photons are just coming to the end of their life. I guess I've got 2 years of semi regular use out of them. I would describe them as unremarkable and won't being going out of my way to buy again.
I've always rated Mammut Phoenix as a good thin rope, but have not used the most recent incarnation.
Beal Icelines are very good. The current version with the Unicore treatment would probably be my choice.
