Looks like fun - nice photo!
I don't have access to a climbing guide book right now, but do you know what "grade V" corresponds to roughly in YDS (5.?)......looking at the photo, the part of the route below the climber is maybe 5.7-5.8?? above - not sure, looks harder.
Well, You are right, V is about 5.6-5.7. But on the picture the route climbed turns right just below the slabs. routhe on the slabs is "Mu-mu-mu", which is VII (5.10c).
