In reply to Le Chevalier Mal Fet:
They can say what they want but i'd rather they didn't hence they might be met with tuneless singing or a STFU.
I'm sure most people including me read the guidebook description, they're usually well planned to give enough to do the route but not enough to spoil any surprises.
if it was you who I sang tunelessly at - fyi I did the route and it was much more fun as an onsight than it would have been had i listened to the beta (or was it talk of a death fall from the crux?)
