I bought these yesterday. I was really torn between using the NAP killzones again this year or going back to a fixed blade. After some research and looking I decided to give these a shot. I put them on Easton axis shafts with blazer vanes. I had sighted my bow with a new sight a few weeks ago. With these heads I had to adjust a little. I was still good at 20 yards but noticed a little drop at 30. Once I was sighted in I was shooting well. They fly pretty nice. I tried them on straight and helix vanes and they they seem to fly better with the straight at the longer distances. I shot them out to sixty with no problems. So far my only complaint is that they destroyed my target. But I needed a new one soon anyway so now I have an excuse.
