whit, i was speaking of the axis... these arrows are the most durable of any carbon arrow i've every shot and i've shot many of the most noteable brands and makes... i believe they are probably the best arrow that money can buy for hunting... they make them more straight and with a more consistant spine, but they don't make them any tougher and when you are talking thousands of an inch it really means nothing...
good luck, buy the axis!!!
