Good blog, its a great place to climb. I always thought the longest continuous granite in Europe was in Switzerland. http://www.ukclimbing.com/photos/item.html?crag=3196 at Grimsel, routes 420m long, but I could be wrong.
Etive slabs offer longer routes too.
Maybe longest in England
I was surprised too! I've climbed at Etive and yea it probably is longer however I think its more the Devil's slide is uninterrupted by overlaps etc - well that's the reason Doug Scott was there guiding there at least!
I hadn't heard that claim either, but could quite possibly be the longest single sheet, as in, no exfoliation flakes. The biggest single sheet at Etive is the 200ft, Central one.
