I did this route the week before but in reverse. ie went up Carn Liath first then anti-clockwise round the tops, eventually carrying on to Sron a Ghoire and carrying on off the end of the ridge back to Aberarder. Stunning views at the top if you can get a clear day. Not wanting to hijack the thread but here's a couple of shots from the day:

The summit of Carn Liath can be seen at the end of the ridge and is taken from near the Stob Poite Coire Adair summit with Loch Laggan below in the distance.

Here's "The Window" between the Creag Meagaidh and Stob Poite Coire Ardair. Remnants of snow can be seen to the left of The Window on the ascent to Creag Meagaidh.
