Just some comments for your consideration.

I cycled John O'Groats to Lands End last year - my colleague used a GPS system while I used paper maps (printed off from the electronic OS 1:50,000 series with route overlaid); by printing only the maps we needed (about 60 double-sided A4 sheets) the weight of paper was kept reasonable (less than 0.5 Kg). We found that each of us went wrong from time to time and were corrected by the other. On one day continual rain made the paper maps for that day unusable. Then rain from the previous day had penetrated the GPS system and made that unusable for a day.

If you are happy with mapreading and can keep the maps dry then you don't really need a GPS. If you want a belt and braces approach then use both paper maps and GPS. Having two or more people navigate using different methods is a very good idea. Don't use any navigation system which relies on internet/mobile phone connectivity, since there are quite a few areas where you can't get a signal (like about a third of the trip for us).
