I spent roughly a year combing the internet, note-taking, and experimenting with all the various Aeropress methods, including those that won the competitions; I can say conclusively that I was unable to find a method that gave as good results as the stock instructions included with the press. Not surprising given its origins - its inventor is also very much an experimentalist (the same guy who invented the Aerobie frisbee,) he hangs out over on the CoffeeGeek forums where there have been lengthy conversations about improving the technique, but he's open in acknowledging that the stock instructions were arrived at by trial-and-error and blind group taste-testing.
The only qualitative improvement I found was using a Melitta micro-perforated filter instead of the included plain ones, this lets through more of the top-end fruit/citrus/floral overtones like a good pour-over. Once I tried that, I never went back to the regular filters.
