You know what I think would be interesting, taking a mythbusters approach to some of the more prevalent beliefs. Do an experiment, if no discernible difference, try to force a difference. Marshal, or one of his cohorts, did this with the 90min boil for Pils DMS. Obviously can't do this with all, but some would be interesting a doable.
Take Ken's pure pitch idea. If there is no difference, try a 1/4 package.
