I have yet to try baking a mostly white loaf. Currently, I have been using a recipe from Zero Waste Chef, which consists of 60 percent whole wheat, 20 percent whole rye, and 20 percent white bread flour. Sometimes I split the whole-wheat portion between kamut and sprouted whole wheat. I've tried 100 percent whole grain from a tutorial on YouTube. Regardless of which recipe I use, even the loaves that don't turn out as well as I would like are tasty.
An advantage to white flour is that it rises more readily.
One of my problems is that the crumb in my loaves is not open enough; another is that the loaf is denser in the middle than on the edges.
