DD - You're right, the last thing we need is any extra pieces of paper. Printing out GE images for really difficult waypoints can be useful though.
Main point was trying to get across is that when operating around busy airspace or planning a long unfamiliar nav, we should all the tools available to us.
OK, 3-1 time spent on prep might be a bit much, we're not the military planning a bombing run, but an extra 15mins to visualise a route doesn't seem too onerous to me.
Happy flying
