CH-47 is almost as good at high and hot altitudes as it is at sea level, while the CH47 is primarily meant for sea-level.
Really, I'm thinking our best bet would be to find some good, used, in term choppers suited for Afghanistan (8 older CH47s), then hold a competition between the CH47 and the CH53 in all environments to see which is the better aircraft. Then put the 8 Chinooks we ought into mothballs, to be brought out again in wartime if the CH53s prove themselves to be incapable or lagging in certain theaters.
