careful Bill! lets not say something as an absolute about "bow depth" in the resistance to pitch pole! some young gun out there may take that and run with it and never incorporate the correct principles. As you know, (and have used in your own designs) any reistance to "pitch pole" has very little to do with the actual relationship between the bow and the stern! what does effect the "resistance to pitch pole" is the reduction to forward motion of the bow through the water when put under extra forward and downward pressure. As you have said your self, the easier that the bow will drive with little or no reduction in forward speed the less likely the hull is to "trip" (or pitch pole)
