I agree Len. The thing I'm most concerned with as far as carbon arrows is the nock end splitting due to hits from group shooting or from another's arrow. I broke a Gold Tip arrow once while shooting it from a 15 pound kid's bow at a novelity shoot. Shooting with two fingers under the arrow's nock, it fell off the string at the shot apparently and the string hit the side of the shaft, breaking it badly with splinters everywhere. That was enough for me to rethink my future carbon purchases. I have some more carbon arrows on order, but will be inspecting them after every shot from my powerful bows.
