In reply to Richy boy:
If your a competent climber you'll have no bother with the technicality of it. Don't be tempted by the gully to the right - its bloody horrible, loose and prob more dangerous than the ridge because of it! At the top of the ridge, don't follow the continuation of the gully (the obvious way) as its scree horribleness - walk up to the wee col between the crowberry tower and the mountain proper and scramble up there - much better, more solid and tops you out right by the summit.
On the approach, as you come to the top of the screes you'll see a tree, bear right at the tree and cross a watercourse / drainage line and head up from there. you'll see the unmistakable rannoch wall above you and curved ridge to its left.
If you head up past the tree you'll end up on D gully buttress which is about severe if climbed directly. you wouldn't be the first!
up to yourself whether to carry ropes / rack etc. I wouldn't as its technically really straight forward for a climber. I've been up with folk climbing no harder than vdiff who didn't have a problem scrambling up it.
Cheers,
