anyways as i was saying...... aluminum arrows can blow up on you too. alot of the time, a carbon arrow blows up on someone because they arent checking their shafts. also in this day and age, a person doesnt need a 600 grain arrow for hunting. every animal i have harvested with a bow, has been shot with a light carbon shaft most with expandable heads. all have been complete passthroughs. twice as strong as aluminum,economical, small diameter, flatter trajectory(generally speaking). what more in a hunting arrow could one ask for???? all my own opinion of course....
