In reply to IainL:
We just got up early did most of the long walk-in in the dark and were comfortably first on the route. The sun starts to hit the crux slab soon after dawn in September so friction is best before it warms up. My main concern was I couldn't see the bolt next to the crux, in the slanting light gliinting off the crystals in the granite. Finally spotted it and clipped it next to my ankle.
For Regular Route on Fairview we sat ready in the car hoping the temperature would move above freezing before other cars arrived, playing Muse's Absolution to maximise the tension. Even then climbing as a three (with one not a little freaked by the scale) no one caught us. Most other routes we never worried about queues and the only time we nearly got caught out was trying to climb The Grack quickly before heading out for the flight home... a lovely woman who was learning to climb let us jump the queue to the annoyance of her guide...glad she did as the guide was super slow... we took pictures of her on pitch one as we finished the abseils.... turned out she was the mother of a superstar climber.
