In reply to Pids:
It's only hearsay on my part but I'm not sure anyone looking for comfort zone climbing 'up to VS' might thank you for The Long Climb. Would anyone who's actually done it care to offer their thoughts?
OP: Raeburn's Arete (S) into NorthEastButtress (VDiff) gives you several hundred metres of excellent *** climbing, topping out near the summit. That's one I can actually recommend
Observatory Ridge (VDiff) is great too
And if you're looking for more of a scramble with occasional easy pitches thrown in then you can't go wrong with a summer ascent of Tower Ridge
