For my trip to Skye last year I really wanted the Skye Scrambles guide from SMC. It was out of print and hard to track down. Eventually I found someone who offered a loan of a copy and along with it came Ralph Storer's '50 Best Routes On Skye'. An excellent little book, most portable with a special style of writing, at once terse but authoratative.
Hard then to resist this when browsing Amazon for books on Scottish Mountains.
And I think there's more in Mr Storer before he gives up the pen!
