Charts over here in France are paper, so I mark one line in 5B pencil from departure to destination, and also an arrow with the Wind direction. And thats it.... no fan lines, no 5 min marks, nothing else. I have a Plog. And the other thing I use..... (wait for it, loads of incoming after this statement..) .... is a Garmin 196 GPS!!
KISS.
