I suppose many of you might know this already, but for those that don't, Sustrans are selling their National Cycle Network maps with a 50% discount at the moment.
I've found these 1:100,000 maps useful for route planning and following - they've got larger scale inserts of the town centres where it's easier to get lost. I confess, I've used them alongside OS 1:25,000 or 1:50,000 maps, rather than on their own, but they do have mile markings and elevation plots.
So, consider them an adjunct to your Spokes and OS maps, but I can easily recommend them with the discount.
