I've heard good things about DCA arrows and I know a few people who shoot them. Straightness isn't an issue because carbon arrows are generally gonna be straight or broken. They're not like aluminum, which can bend. $50 per dozen is a hell of a good price for carbon arrows, too. I'm pretty sure you can't touch a decent aluminum shaft for $50/dozen. If I didn't already have a bunch of GoldTip 7595s already ($100/dozen) I'd try some out.
