Great detail on this @duncancritchley! Drummond's ascent is pretty interesting, what do you think to adding a separate climb in to record his effort?
I've not done the route so I don't have a sense of how different the climbing is. I don't see it credited as such anywhere so probably not. Mick Ward describes Drummond as "bizarrely named" in a slight miss-step in his otherwise excellent UKC article on Pete Crew and there is the consistent sense that he doesn't get his due.
