Penetration aluminum or carbon arrows. Join Date Apr Location U. These days, it seems more hunters are filling their quivers with carbon arrows. February 22, Field Test: These days, it seems more hunters are filling their quivers with carbon arrows. Is there a noticable difference in penetration. If you buy a doz carbs and you only get 6 to tune what are you going to do with the rest? Sometime the lighter arrow will have more energy and sometimes the aluminum will. They can take all the punishment you can give them and continue to perform as if they were brand new. Many were cut off for younger shooters or made into pens for hunting buddies.
