ok so still not knowing what alum arrow...lets just say they are 2117 GG with a spine of .407
at 26.75" that arrow will be about 475grains at your draw shooting 220 fps with 51.06 Kinetic Energy
now if we shoot a 400 spine Victory arrow for 69.00 dz will be about 370 grains
would shoot 255fps with 53.44 kinetic energy
so for hunting I would shoot the carbon arrow over the alum.
the alum arrows you can get for 38.00 will have a conventional nock ...not as good as the super nock that carbon arrows have or better alum arrows have....alum arrows are very straight and have real good spine ...but you will get more life with the carbon.
I still shoot alum arrows for indoor shoots cuz they shoot so good ...but it is 20 yards ...slow, but hits the same spot..but I shoot X7 alum and they cost 90+ a dz. ...so some times cheaper is not always better...
I hope this helps....alum will fly just as good as carbon...
if you need more info call me I can talk better than type...
