thanks for your reply jeremy, i had not thought of using info in that manner , interesting and useful. no hidden meaning in my question, sorry if that was implied.

No worries Bill.

After having to stop short at Oban bothy on day 1 this year because the terrain had proved more difficult to traverse than I expected, and then ending up trapped at Oban for 36 hours, I am perhaps a little more sensitive to the question "What should I expect the terrain to be like?" than in previous years!!
