[@JaceBeleren] going by my knowledge of swords and not specifically zweihander, swords have about half of their weight in the hilt, below where you grab the sword. That is why giant 5-10 lb swords can be handled so easily if you are strong enough to pick them up. You'll occasionally hear people saying "the weight is off." If the blade is too heavy, the blade constantly wants to dive. If there's too much weight in the hilt, then it is difficult to swing the sword downwards, as you're fighting to lift the hilt towards yourself.
