I CAN say they are better.....CARBON!
Truth be told, I never shot a carbon arrow til I started shooting stick bows again about 8 years ago. For quite a spell, I shot high tech/high dollar wheel bows and the only thing I shot out of them were the best aluminum shafts. Although they were super accurate, they cannot compare to the durability of carbon! (and the accuracy is there too) Although I love the romance of woodies and still shoot them too, the carbon shaft is the best thing since sliced bread for the stick bow shooter! This is my opinion.
