I shot the heads with straight and right helical fletchings. In both cases the accuracy was good and If I had 1/2 points I may have given them a 4 1/2 in the accuracy dept. But I don' t have 1/2 points and with the claims the manufacture makes I was tough on them as far as the accuracy score goes. I see like this, if you state it for the truth the head better preform.
