but the fact that they can and do bend like aluminums
They can bend, and do bend..but NOT like straight aluminum.
As I' ve said many times before they take nock end hits extremely well (better than all carbons), and most people who have problems with them bending are the guys I see who can' t get one out of a 3D target without twisting the thing like a pretzel.
You can' t pull on ' em like an all carbon shaft, but ACC' s are certainly more bend resistant than straight alum.
I sent you some. Shoot ' em for awhile. Draw your own conclusions
