In reply to Jim C/Saor Alba.
Thanks Jim, I did google and had a list of numbers - I suppose I was after recommendations from people who'd done similar.
Saor - I have seen that rank but forgot about it so I'll add that to my list of possibilites.
I was intending to go up and over Aonach Mor/Beag in the next couple of days but the forecast wind has put me off, I'll do something further south and leave the Aonachs until next time.
