Everyday Buttermilk Waffles: Whole Grain Waffles Variation

I have to say most of the time when you use whole grain flour in place of regular flour (esp. if you only substitute about 1/2 of the amount) the result will be very similar to the original recipe. For some reason this is not one of those recipes. I tried this variation and it was terrible. I would maybe try it again and only substitute 1/3 of the flour for whole wheat instead of 1/2. Whole wheat flour just absorbs a different amount of water then AP does so I think that was the issue that made the final product inedible.
