In reply to Grahame N:
> However I was surprised to find that I’ve only done 551 routes out of the 1760 in the book, after 45 years of effort. So lots more to do and a few new crags to visit.
I couldn't resist counting. About 460 for me over 42 years, though I was quite surprised how many routes I wasn't sure whether I had done or not - I stopped ticking guide books or making lists many years ago!
Going through the whole book, one thing that struck me was the selection of just a part of a crag, leaving out a neighbouring section of pretty much equal quality and grade range - this might short change a visitor making a visit. Two examples would be the section of Ardmair right of Big Roof Buttress and Big Flat Wall at Latheronwheel, which I would have thought is the most appealing part of the whole crag. Also, as with Shetland, one wonders at the value as an actual guidebook for Lewis; if you were making the effort as a visitor to go there, you would want the option of quite a few more crags and therefore the definitive guide.
I was also surprised at the crags I had never even heard of.!
It must have been a nightmare making the selections.
