One of these paired with quetzal harvesting will give you the fastest harvesting for metal, crystal and obsidian. Just level melee and let the quetz take the weight of the Anky.

To collect metal faster: Call your friend from the tribe. One goes to Argen and another to Anky. Then take the Anky with the Argen and go find metal. Fly near the ore and activate anky's attack in the air to collect the metal. When the Anky has a lot of weight, go to a safe area and pass the metal to the Argen. Repeat until Argen is full.

Metal, Crystal and Flint. Can be carried by Argentavis. Metal got 1/4 weight in it.
