In reply to Chris Craggs:
Grading such a route is quite difficult. Before I did this I had just done a whole series of quite hard routes including West Face Route at E5/6b but thought that Deja Vu was far more serious even if it was technically easier. Chris, you may be right with the grade but as you know, once you start the moves traversing right, there is no way back. To me it is one of those routes that, perhaps shows up the problems of our grading system, or maybe it is just under-graded, if the consequence of a fall is taken into account.
