Thanks All!
Captain, glad to hear you had a good weekend too, you certainly got loads done, very jealous!
Andy, there is a cryptic sentence in the guidebook description along the lines of "...a steep wall, the crux if climbed direct, but there may be another way..." and I think this was our first route finding error as we tried to find said other way. The top section was completely our fault - we had the guidebook (as suggested by sgl) but didn't look at it and just went for the obvious feature above us. So pilot error!
Senzubean, it looks like you climbed the correct grade IV finish to the left of the direct - you can see the direct above the rope in your first photo, but your second photo shows you climbing the lefthand corner
Cheers,
Dave
