In reply to afshapes:
The bottom half of the route is easy. When I did it me and my partner just climbed together with 30 metres of rope between us and always at least two bits of gear. We continued like that till pretty close to the half way ledge.
This only worked as the route was well within both of our leading grades and we were both very evenly matched. We were also first on the route. We started very early. We were actually climbing by 4am.
Make sure you find the base of the route the evening before. Literally go to the start of it so you know exactly where it is.
I am not saying you have to move together as it is obviously potentially very dangerous but you definitely need to move pretty quick to do it in a day.
We were finished by 2pm when we did it.....so still were not that fast.
