In reply to 001HELEN:
Up North West the best of them are probably Goat Crag, Creag nan Cadhag, Glutton Crag, Creag nan Luch
All the new developments up there are covered in the 2nd Edition of 7aMax Scottish Sport (2015)

More due west, Tunnel Wall (Craig a Bhanciar) in Glen Coe is good, albeit hard and a bit neglected.
Out west from Ft William - Rannochan and Black Rock (Arisaig) are both worth a look if you are in the area.
Arvorlich is not really much to write home about
Have fun!
