In reply to KennyWright:
Time variable, bit like tower ridge, some parties take 2-3 hours (once on the ridge proper) in good conditions, others all day. A very good outing.
Consider your approach, given preceeding wind direction and potential avalanche risk. Both the Glas Toll bothian approach to the west, and coireag Cham approach east are relatively sheltered so can collect wind slab. But give you two completely different aspects to approach via. There is also the direct approach via Terminal buttress, which gives harder climbing and makes a longer day.
