I would not agree with that but each their own, if I'm going to pack horns out from some place that it's on my back it going to be a hog and if I need to loose as much weight as possible I'm caping it out and loosing the lower jaw and anything else that can come out which makes the skull not that heavy and the best way to keep the skull plate intact, I intensely hate rolling around an elk head trying to hack out the horns with a small saw, I'll pack it to the nearest saws all!!
I really like ribs but no way I'm packing them out as a rack, that alone makes an extra trip and unless horses are available which would be packing more equipment like an axe and saw the ribs come out minimalist as possible but on a whole elk they go through the saw and are most excellent.
I have not figured out the guttless method on an elk which does not loose significant meat, by the time I'm done there is nothing holding the gutts in and they just get in the way unless removed.
