The two strip maps are still available as pdf files. I downloaded them from somewhere ??? don't remember where, a couple of years ago. They can be printed out by a plan printing company.
You need to be aware of minor changes in the route over the years which will not be on the OS strip maps or possibly in the Wainwright book.
Personally I think a couple of the new lines that have emerged such as the sidling path into Scarth Gap and over Haystacks for instance are are more aesthetically pleasing - to me at least. There are several recent threads that discuss them.
On our crossing in 2009 we found the Stedman book good. I felt the footprint maps were poor and much preferred the Harvey maps which we bought en route as a replacement. The reasons we found the footprint maps inadequate are the lack of a referenced grid so you cannot use a gps to locate your self or locate a point from a given grid reference. Also the scale varies from map to map. As the legend says "map scale is approximately 1:50,000" - I don't know how they have the audacity to sell them.
