I think Chuck is just telling us why "he" prefers Aluminum.
Easton makes carbon arrows too as well as owning Beman

Not sure they would "pay" him to specifically steer everyone away from carbon arrows?

I used aluminum arrows for many years and they worked fine, they still do.
Been shooting carbons for the last 5 years or so and they work also.

My advise would be to try both and see which ones work best for you and your set up.
