Thanks guys! We tackled it from Lost Valley side, east to west i think (uploaded photos show it the opposite way). Yeah the clouds were fantastic, on the north side we couldnt see a thing compared to the south which was clear all day, very dramatic as you say. You really need to be careful if its windy, at points the wind funnels up through parts and gathers pace - not good if your on a pinacle!
We've done a few Munro's but not for a while, definitely caught the bug again after this!
