In reply to Simple Simon say's:
(1) Do it clockwise, so you go up the awkward part onto Corrag Buidhe Buttress rather than down it
(2) Definitely not the superdirect way on the right, which is about Diff and very exposed. But as Dan says, the far-left low-level traverse route (followed by a long ascent up a grass/choss gully) is a waste of a wonderful ridge.
(3) So, take the intermediate way (see Dan's route card or SMC Highland Scrambles North) which involves slabby scrambling for what I recall as 20-30m. The SMC guide gives Mod for this (via nice flake crack at left end of slabby area) but there's more than one way. A confidence rope might be in order for this bit, but afterwards it's easy scrambling, with ledges round the various low (5-10m) pinnacles (though they're great fun to clamber over on a nice day).
