Here's another report of a walker combining An Teallach with the route done anti-clockwise.
http://www.stevenfallon.co.uk/anteallach.html#I think I am going to wait and see what the weather is doing. There are a couple of options. Limited bus service means I am thinking of setting off on the route on Sunday morning rather than turning up at Shenval late Saturday night when people might be trying to get some kip. Any pointers are more than appreciated
