I know it's a honeypot but there's a hell of a lot more to the S. Highlands than Udlaidh!!! How about emailing a few S. Highlands suspects like Postie to get the overall picture?
The Coe itself is less reliable than many crags further South.
> There is often some nice pitches to the right of the main guidebook routes (looking up at the crag) !
And to the left (where we climbed yesterday on finding most of the main lines taken), but these northern icefalls (as we discovered later) get a passing mention in the guide. Enjoyable climbing with plenty of ice, but much of it hard and brittle.
