In reply to gforce: In reply to Robert Durran: You're quite right, Hybrid Vigour was total quality..one ascent in 18 years shows it had vintage classic status!!
The corner to the right of Cougar is unclimbed; Things are always harder than they look at the Dubh Loch!
It looks from the photo above that there is a shelf at the bottom of the rock scar which might be traversable into Ascent of Man, which is about E2 5c to the top from there IIRC, you might then be able to access the top pitch of Cougar from there, but it would be rather circuitous and pointless I fear.
