I was shooting arrows with a straightness of .006 and had trouble grouping. I took the advice of Arthur P and BGfisher and bought some arrows with a straightness of .003. I took 3 arrows of each staightness and at 20 yards there was very little difference but at 30 yards there was a significant difference. The .006 at 30 yards did not group as well and were not as consistant as the .003. My grouping and acuraccy has greatly improved with the new arrows. Thanks for the advice.
