Absolutely blind bake your single piecrust. And do not bake at high temperature. Stella Parks wrote an article on blind baking at 350°F temperature. And she’s correct this is a far better way.
I freeze my piecrust for about 15 minutes so I do not damage it. I gently crumple a piece of regular aluminum foil, then open it up. I form it to the inside of the crust taking care to get it in the edges. I’ve been lifted out to make sure it does not stick to the crust before I set it back down.
I use rice as the pie weights. I don’t like to use beans or ceramic pie weights as they’re too heavy. Stella Parks uses sugar since you can use toasted sugar for other things.
I bake my crust to a light golden brown. Stella Parks over bakes hers IMO. but to each their own.
You can also blind bake double crust. And in fact it’s recommended by many bakers. Erin McDowell has a good technique for blind baking double crust. See link below. I also think McDowell over bakes hers but again to each their own.
Most so-called ”textbooks” are riddled will errors.
The one book that is well regarded and is in fact used by many professional pastry chefs is Advanced Bread and Pastry A Professional Approach by Michel Suas. This is my baking bible. There’s some things in this book that is strictly commercial, ingredients in the equipment that you’re not going to use in the home setting. B the science and technique is rock solid.
Suas actually founded and continues to run The San Francisco Baking Institute. Aside from training thousands of bakers, and some of the award winning bakers in the world Suas is also a consultant. Every baker who is anyone in the US has turned to Suas for assistance including Thomas Keller of Bouchon Bakery; Chad Robertson of Tartine; Steve Sullivan of Acme; Nancy Silverton of La Brea. Suas’ client list reads like the Who’s Who of bakers in the world.
A few months ago I was in a class conducted by a master baker. This baker won the gold at Coupe du Monde de la Boulangerie. One of the participants asked for recommendation on baking books. He said the only baking book he would recommend is Suas’ book.
Suas is business partners with Belinda Leong in b. patisserie. Their bakery won the James Beard award in 2018 for Outstanding Baker. So his work translates into the real world.
