Having the same straightness and weight tolerance specifications as competitors high end shafts seems all well and good, but shoot them into a block 5 or 10 times, or skip one off the top of a target, then measure your straightness... It becomes very apparent why some "pro" shafts with 0.01" tolerance cost more than others, AND why those shafts have high reputations. I've gone through a lot of shafts, and I'm not at all saying that DCA doesn't turn out a great hunting shaft at an affordable price that almost makes me want to convert to buying lower grade shafts and replacing them 3x as often, but when it comes to running arrows a lot of shots on target through an aggressive cam bow, you really do get what you pay for in terms of arrow life and resiliency.
