Ive broke a couple of my day six. One had cracked carbon after i shot a nock. The other broke right behind the outsert after it went through 12-15 inches of dirt and into a rock. The factory fletch job was terrible. Had to swap out factory nocks for easton g nocks to get a positive click when nocking an arrow. A 620 gr arrow going 261 was also a little overkill when my arrow would be all but completely buried in the ground after zipping through a whitetail.
