I prefer the one I was taught on my CPL. Two fan lines (one at either end of leg). Once you have ascertained your position, estimate how many degrees you are off track from your starting point, then estimate how many degrees you are off track from your next way point. Add the two numbers together and apply this correction. It gets you to your waypoint in the most direct route. It's so simple I don't know why others don't teach it. And before cries of "Off side referee", my CAA examiner seemed very pleased with this method and subsequent students have never been criticised by their PPL examiner.
Oh, and I'm with the chaps above - put the chart away and don't even think about looking at it until a couple of minutes before a waypoint or a 'checkpoint'.
