In reply to Georgert:
Thanks for the input, all! Took the advice of the earlier responses and went for it.
A wrong turn (first visit) took us up the approach to Great End Crag... so we really thought we'd be queuing once we made it to TP. But lo and behold, we had the entire crag to ourselves for the whole ascent.
Such a special route – and made all the more memorable thanks to the breathtaking views of Borrowdale on a sunny morning with not another climber in sight (until passing roughly 10 as we packed our kit / descended back to the valley!).
