What are your tips for Perfect home made pie crusts

I Have this all butter recipe for pie crust in stead of using crisco, well, I have never been able to roll it out and keep it in one piece long enough to get it into the plate. I normally give up and go for the crisco /flour recipe and that one usually works for me.


What are some good tips, I got mine really cold and it still fell apart. Or rather, what am I doing wrong.

the recipe for the all butter is as follows

2 1/2 cups all-purpose flour, plus extra for rolling
1 cup (2 sticks or 8 ounces) unsalted butter, very-cold, cut into 1/2 inch cubes
1 teaspoon salt
1 teaspoon sugar
4 to 6 Tbsp ice water
Method
Cut the sticks of butter into 1/2-inch cubes and place in the freezer for 15 minutes to an hour (the longer the better) so that they become thoroughly chilled.
2 Combine flour, salt, and sugar in a food processor; pulse to mix. Add butter and pulse 6 to 8 times, until mixture resembles coarse meal, with pea size pieces of butter. Add ice water 1 Tbsp at a time, pulsing until mixture just begins to clump together. If you pinch some of the crumbly dough and it holds together, it's ready. If the dough doesn't hold together, add a little more water and pulse again
Remove dough from machine and place in a mound on a clean surface. Gently shape into 2 discs. Knead the dough just enough to form the discs, do not over-knead. You should be able to see little bits of butter in the dough. These small chunks of butter are what will allow the resulting crust to be flaky. Sprinkle a little flour around the discs. Wrap each disc in plastic wrap and refrigerate at least 1 hour, and up to 2 days.

4 Remove one crust disk from the refrigerator. Let sit at room temperature for 5-10 minutes in order to soften just enough to make rolling out a bit easier. Roll out with a rolling pin on a lightly floured surface to a 12-inch circle; about 1/8 of an inch thick. As you roll out the dough, check if the dough is sticking to the surface below. If necessary, add a few sprinkles of flour under the dough to keep the dough from sticking. Carefully place onto a 9-inch pie plate. Gently press the pie dough down so that it lines the bottom and sides of the pie plate. Use a pair of kitchen scissors to trim the dough to within 1/2 inch of the edge of the pie dish.
