Carbon is more durable for sure if you get heavier hunting rather than target arrows. You will likely shoot something in the .400 range. Do not cut carbons to length and expect them to shoot perfect. Youu need to start full length and bare shaft tune cutting as little as 1/4" at a time.
Aluminum seems to be more forgiving over the range, but I also have some bows that shoot a variety of spines fairly well.
