Sounds good, just finished reading an article about them in Bowhunt America magazine (Feb/March 04 issue). The author/tester shot one of the ST Axis arrows through a 1" thick fireplace stone...it split the stone. Then he used the same arrow and shot at a 2" fireplace stone....the arrow went 1/2" in....the shock popped off the nock. No damage to the arrow. It still shot into the same small groupings as the other Axis arrows. That's one tough arrow...that's for sure. Don't know the price of them yet.
