In reply to Coel Hellier:
Gosh, now you ask. It was around 2013 so you'll have to excuse vagueness, but I seem to remember placing a no.3 friend in the big slot and then getting hugely bunched up and faffing a lot. Upon further inspection there was some kind of rather crap gaston crimp and then a longer move to better holds. I think the confusing part as well was that it actually went a little sideways but that wasn't readily apparent from below.
Now that I think about it we also did an E2 and E1 to the right, both of which were excellent, but I couldn't tell you the names.
