I first walked/climbed this route back in 1971 just to get away from the lone bag piper droning over his massacre. This ridge is one of the classic Scottish ridges with a long wonderful high, airy scramble etc and a dangerous gully descent straight down into Glencoe near to the Clagaich pub if your mad enough. Its a long day out but a good one even better still in mid winter. This year the ridge was the same with a few changes the start is now a stone stairway, theres a queue and the bag piper is Chinese who has a Phd in Forestry, sadly the pubs no longer a wood shack serving draught guiness and whisky its now a classy hotel "Were did you go lassie go?"
I think that Liathac Ridge was steeper and a more challenging mountain experience summer or winter but my opinion in climbing terms is very humble. Here's a link to a great website whicg gives a route description http://www.walkhighlands.co.uk/fortwilliam/aonacheagach.shtml
