Fletched Aluminum Arrows
Aluminum arrows are heavier than carbon arrows, so it's going to allow more efficiency with the bow. The energy is going to be transferred basically equally as a shot, it's not going to lose that energy like a carbon arrow.
If an arrow hits a rock or something very solid, the wood and carbon would be definitely gonna break, while aluminum will probably bend before it breaks. A lot of the times you could just simply eyeball it and then readjust them.
