I'm getting ready for new arrows. I noticed the arrows I've been shooting which are the Easton Aftermath have a straightness of .005. I notice other more expensive Easton arrows show a straightness of .002-003. I have a hard time believing I will be able to see the difference when that translates to arrow group. Anyone agree or disagree? I've been happy with my Aftermaths over the last few years and don't consider myself a tack driver, but just want to make sure my thinking is correct?
