All I know is that I have a basement full of junk BENT aluminum arrows and they were shot out of an old Bear Alaskan II bow that was probably lucky to fling an arrow at 200 fps. Can't imagine a 270-280 fps bow firing an aluminum arrow into something other than a target without them bending. I like to shoot squirrels and rabbits in my yd. Carbons are the better choice for me.
