RE: ACC arrows...
I can't comment on Blackhawk's aluminum composite arrow. Haven't even seen one, much less handled or shot them. But I have handled and shot ACC's. If I were to ever go back to shooting my compound, there would be no other arrow in my quiver. BUT...! I am a good enough shot to appreciate the quality. I can appreciate being able to shoot a 4" group at 60 yards vs an 8" group.
If your arrows' accuracy is limited by your skill, then you may not find ACC's worth the money. If you find your accuracy is being limited by the quality of your arrows, then they will definitely be worth every penny.
