Carbon for me!!! I don' t think I' ll ever go back to aluminum again. First of all there is the increased accuracy from carbon, second the durability, it is either broke in half or just fine. In creased speed is another reason wich inturn results in some cases more kinetic energy. One thing I make sure of when huinting with carbon arrows is that I use an arrow with atleast 9 grains per inch weight, that way I know i' m getting enough kinetic energy out of my bow.
