Yes, I agree it's good to be able to discuss these things and get others' perspectives and tips, both online and on the hill.
My heart was in my mouth today when, from 1141, I observed a couple of people climbing up Alladin's Couloir. I hope they made it...
Worth mentioning that a 60m ab from near the bottom of said route gets you on to shallow slopes without a sketchy run out.
A useful thing I've got recently is a clinometer app for my phone. Of course having it is no guarantee of making the effort to use it when it's dark, you're knackered and you'd just like to believe that the slope you're on is fine. My partner and I got away with it coming back down into Sneachda from the col to the north of Mess of Pottage a week or two back, but it was a bad decision, stemming from bad planning in not thinking sufficiently before the climb about descents - not just the approach! If we had, we'd have climbed with bags that day.
