Thanks everyone for helping me think through this one!
I have never used rice hulls but it does not seem that using more would increase chances of channeling. More may be a waste though.
I don't think that mixing your grains before adding to the mash water would make any difference. When I mill my own I do one type at a time so they are layered and have never had a problem. But, you must stir the mash really well.
I do agree that you need to make sure the crush is good.
