RE: Aluminums???
Carbon- Out west on the mountain, fall down, slide 150 ft, stoped by a large rock, bow falls another 100 ft. tumbles,,,, etc. Which arrow do you want in your quiver?
I know they are outdated but I shoot sme epsilon heavys - I practice for 3D out to 100 yards and throw muzzy 100s out to 70 yards with very good accuracy. Just my experiance.
ALU- Nothing wrong with them for most, you can buy 2 for one so the bending or breaking is really not an issue for me.
It comes down to utility for me - my equipment needs to be durable, I don't take care of it worth a crap, yep I'll admit it, so I need to know that it will work when called upon.
