In reply to Jamie B:
Agreed , we were never quite sure whether to push on to a better belay or not , in good weather , there is little need for so much detail
In bad weather & particularly in bad visibility ( & on our ascent the weather gradually worsened ) , not going off route is important , particularly as most off route excursions are harder. This is fine if you are great on grade 6 not so if you are not !
