Although I think that in general, carbons are more durable than aluminums, I don't think it's a major factor and I certainly wouldn't choose my hunting arrow based on the difference in this aspect. I've seen many a carbon arrow break when it shouldn't have. Defects are more easily hidden and I think the risk of injury is higher.

I'm not sure I've ever measured a perfectly straight carbon. They may not bend, but they don't have to. They come pre-bent. At least compared to aluminums, they are not as straight, unless you want to spend a lot of money on the premium models. Spine is almost always less consistant, both in range on a dozen and in the different sides of an individual arrow. It doesn't matter much when shooting field tips, but you have to know what you're doing if you shoot fixed blade broadheads on the lower-end models.

All that said, I still vastly prefer carbons. The reason - the ability to configure them with a very high FOC. I'm completely convinced of the significant advantage of shooting extreme FOC arrows that have been properly spined tuned. I configure them with a very stiff shaft and put lots of weight on the tip to even-out the spine. This can't be done on an aluminum without doing some creative arrow making where you manufacture your own tip weight. If you manage it, you'll probably end up shooting in the 800-1200 grain area. Heck, you can't get most people to even try something in the 550-650 gr range, much less something that heavy. Anyway, to me, this overcomes all of carbon's negatives and is a significant reason to shoot carbons, vs aluminums.
