"We should remember the warning of the wise Grail knight in Indiana Jones and the Last Crusade: "You must choose, but choose wisely, for as the true Grail will bring you life, the false Grail will take it from you." Choose the highest-yield material and you can be an idiot and enjoy stunning success. Choose poorly and, as the Grail knight implied, you're screwed no matter what. You'll chase your own tail for years."
