In reply to CurlyStevo: The only route I've done up there is the Cracks, which is good, and it was the only dry line at the time. We didn't have a guidebook and went up the dry, easy looking bit! Wasn't the most sensible idea I've ever had but it worked out well.....
So anyway from my limited experience the cracks was dry in wet-ish conditions. I think you can escape after P3 or 4 (can't rememebr which) if it's soaking higher up.
