Ray, if you install your HIT inserts propery you will have an amazingly durable insert. Just like in the video that Easton shows I blew a shot when I was shooting in my shop and it bounced off the concrete wall and flipped off the nock. The shaft was still intact. No cracks or any damage. Still straight as an......... arrow and still shoots straight! Don't forget to square the end of the arrow before installing the adapter ring.
