Pinwheel, assuming a well tuned bow (which should be a given for most, I'd hope), are you saying that a fixed head will out penetrate a quality mechanical in every circumstance, whether all soft tissue (double lung no ribs) or straight through the shoulders? Again, I'm only talking whitetails. There seems to be a bunch of people shooting steelheads or snypers that would differ with this line of thinking.

Have you tested this theory out to arrive at your statements, or have you seen such testing done that convinces you? I'm really curious here.
