I think I have a copy of the Skye/Hebrides guide somewhere. I'll have a wee look when I get home.
There's certainly plenty to play on, especially on the West Coast. If you head over to Uig and Valtos you should find loads to do. I grew up in Ness and Point and used to muck about on the sea cliffs, I seem to recall there being plenty of things of reasonable grades that you could play on. Loads of bouldering too, again on the West Side (of Lewis) which is generally a wee bit easier to access.
