My plan is to always carry a pack frame and at lest 6 game bags. I bone them where they hit the ground. I see no reason to bring out bones, skin and the entire head just to dispose of them later. The edible meat of a mammal usually only amounts to 48% of the live weight. So an average buck of less than 200 lbs would bone down to about 80 lbs. I carry a folding saw so if I decide I want the antlers I can just cut off the top of the skull.
Looking at your vid, 'll stick with mine. Unless you had that sled with you when that deer dropped that means you made an extra trip out to get it. With my way 'm only making one trip and not two. But to each his own.
