There are 2 schools of thought here. First, the average archer won't notice the difference in a .005 and a .002. So with that in mind, they will work just fine.

Now for the second thought. All carbon arrows, save the new Maxima's, are all made one stock size and sanded down to spec. The ones w/ the looser straightness are the "inferior" arrows of the batch, but rather than toss them, they sell them and at least make some money off of them. Not that there is anything wrong w/ them, they are perfectly safe and will certainly kill anything you shoot at, but w/ that in mind......the question becomes.......How loose and poor are the rest of the specs, specifically the spine?

I always suggest buying the best arrows you can afford. For that reason.
