You can't beat brand new aluminum arrows for consistency in weight and spine, and shooting too. But once they've been used awhile they just don't hold up as well. I got no use for bent arrow shafts myself.....once they are bent, they are done. If you try and straighten them it effects the spine, and they will never fly the same again......
I used them exclusively for many , many years. But prefer carbon shafts much more now. Much more durable... The carbon is ether dead straight, or broken. Nothing between.
