Find a quality arrow and then you will not have to "spine test" each one. I use carbon tech whitetail xp's and have found them to be extremely consistant.
They better be. How much are they? 150 a dozen. But I have put alot of time into paper for each one. In the end, it would be worth it. Next year, I will morgage my house and by a dozen.
