Hi, Can someone give me an insight into the differences between the different A4 size spiral bound AA road atlases. (a) The Black cover one is called "AA road atlas"; scale 3 miles to 1 inch; 328 pages; 108 city & port maps. (b) The Red cover one called "AA Easy Read"; scale 2.3 miles to 1 inch; 376 pages; ???. The scale difference doesn't appear to be huge, is there other features that would make me choose one over the other? Thanks.
