I've been making the normal recipe for years by using half whole wheat and half white flour. It is good. I have never had anyone say it tastes bad or much different, and I love the more brown color in the crust. I've made it with both lard and shortening (I prefer lard because it is less processed than shortening).
I've been trying to find ways to eliminate vegetable shortening from our diet. I just don't think we should eat fats that are so firm at room temperature. Just imagine what that can do in our blood stream.
For the past year or two I've been adding flax seed to our diet. I decided to experiment with adding it to pie crust and I found that the natural oil in the seeds that is released when you blend/mill the flax made it possible to decrease the amount of added fat in the crust.

MILL YOUR OWN FLAX
This is how I "mill" my flax seed. It's tricky because you want to pour the seeds in when the blender is running high or med-high. I put the funnel in the top of the blender to keep them from flying back out. I quickly dump my cup of seeds in and then turn the cup over inside the funnel. Blend for just a few to maybe 15 seconds max. Sometimes I have a few rogue un-milled seeds but I don't mind. If you blend too long it gets hot and turns into a pasty cake under the blender blades. You can still use it, it's just harder to get it out of the blender.
You can buy pre-milled flax but I hear it's less healthy. Sometimes it gets overheated and loses some of the vitamins, and I think it would be more likely to go rancid in storage.
I have used both golden and regular brown flax seeds and both work fine. I'd say about 1/2 cup flax seeds will make 2/3 cup of milled flax.
I call this crust a Hybrid because the appearance, and texture is similar to a crumb crust but it's still salty, made from a dough, and baked like a traditional pastry crust.
