I highly recommend that you consider the pie crust recipe developed by food scientist J. Kenji Lopez-Alt when he was working for America's Test Kitchen. It uses a combination of butter and vegetable shortening:
But the really important ingredient is vodka, which adds moisture without triggering the development of too much gluten in the crust. Here's a detailed explanation of why he chose a combination of fats, and why he used vodka in place of some of the water:
Crisco and ice cold water literally have a bowl with ice cubes in it with a little bit of water to use to mix my dough - the less you handle the dough the better
I have tried the vodka that works pretty well too !
The following video is how I made my crust and apple pies for DW and her mom (very good cook) + family. Got lovingly chastised when I stopped, too much effort for beginning arthritic hands.
BTW, that was after our 1973 marriage when I began making Holiday Dinners AND dessert
