In reply to ruthmj:
So many great crags to choose from, and I'd +1 vote for Sheigra and Reif as options when the big hills aren't in. However, to pick up your specific question about long, easy, s-facing routes, Sword of Gideon on the South Face of Sgurr a’ Chaorachain
Sword of Gideon (VS 4c)
... ticks all of your boxes whilst being almost roadside!

There are also great mountain routes without too much of a slog on Stac Pollaidh

Check out https://rockaroundtheworld.co.uk/category/uk/scotland/ for another couple of dozen suggestions.
Might see you up there - fingers crossed for the weather (and easing of travel restrictions!)
