Look mate, if you don't have a medical issue with a class 2, do a full PPL, and why ever not in the cub? Stick an icom in it to do the VOR fix if you have to, or whatever it needs. I fly all over the place on a magnetic compass, no nav aids, and that means no GPS, no ADF or VOR, just a paper map and a compass and watch. If you do the NPPL you are stuffed for touring. Don't worry if the nav takes a while to get, you will be a better pilot by the time you finish. Mistakes are learning experiences, get them in now while you have mother's little helper on board. You don't need a glass cockpit to enjoy your flying. And when you have done it, in a real aeroplane, come to france and you can fly my cub with the big engine!
