I know it's not what you're asking, but I'd go with a CC lower if it was me (I do not have any experience with a Dlask).
Why, besides quality (yes I know lowers are all very much the same) and the Maple Leaf..., re-sale value will be much, much better (and the rifle should prove easier to sell as well) finally of owning an all CC product; as there's little in this world that's better then an all Colt Canada C7/8.
