In reply to blackreaver:
I would think the likes of Pygmy Ridge and Afterthought Arete might be doable in summer(ish) conditions.
Cummingston in winter with a north wind blowing can get a tad chilly, and quite demoralising if it's a sunny day because most of it faces north, but then maybe it's because I'm more used to going there on long balmy summer evenings when the sun sets over the hills of Sutherland and the dolphins are playing in the waves...
Check the tide for Logie Head, there's stuff to do on a high tide, but much more when it's low.
Personally, I'd go for a walk!
