I have been taught to navigate both in the EFT system and the PPL way, and one observation I would add is that many civvy flyers plan and fly very long legs. I have always tried to keep the legs somewhat shorter and use good positive fixes - even if it means going out of the way a bit. I know some people will raise the issue of 'feature crawling' with this method, but I do believe that if you have a shortish leg with a decent half-way (or 1/3 and 2/3) position/time fix without long amounts of time in between them, it gives you the confidence and ability to dump the map in between fixes, fly and look out. Your route shouldn't take you that close to restricted areas etc.. that it means you are paranoid about staying exactly on track at the expense of lookout and sortie management.
