For VFR, I draw a line on the chart too - may as well since already using it for controlled airspace and terrain planning.
Unless one is able to print out sections of the actual VFR chart, showing the route, which is possible (very expensively) with Jeppesen Flitestar ...
"And then, IMHO, is the time to use VOR and GPS and anything else you've got as a back-up."
Better to use the GPS as primary, with anything else you have as a backup. GPS is the best device by far. Otherwise, it's like travelling somewhere, on a bike, with a motorbike on a trailer in case the bike breaks. Aviation tradition says that the bike is the "proper airmanship" way to do it. Outside aviation, nobody would bother to make their life deliberately harder. Of course, these comments make instructors really mad.
