I shoot both carbon and aluminum arrows. I like both It is true that Carbon is more durable.On the other hand, aluminum can be straightened if slightly bent and 20" or shorter Easton xx75 2219 shafts are pretty durable when shot at 350fps or less. I have no problems with them bending when target shooting. If carbon is warped that's it. It will never be straight again. I had a mishap target shooting a couple of weeks ago This 18.5 Easton xx75 2219 443gns shot at 323fps penetrated this pressure treated 1x2 and a piece of plywood that was sitting behind my target at 30 yards. After carefully removing it and giving it a spin on end it had a pretty good wobble to it. I placed it on my spine tester to see where the bend was and to my surprise it still tested at .oo1 straightness at 17" Believe it or not the wobble was from a bend in the field point shank! 2219's are tougher than some believe.
