This year we are making our blueberry pie according to the Cook's Illustrated Blueberry Pie recipe and using their Foolproof crust. This is the single best crust I have ever made, or consumed, for that matter. You have to try it. It's worth following every instruction to the detail in the Cook's recipe, including using vodka alongside the normal water. You can read about the science behind using the vodka in the magazine, but I don't see it anywhere on this link. This is one of the reasons I love Cook's Illustrated so much...they really get into the science behind their reasoning, and explain the methods of testing they used to get to the final version.
