Without going into a huge thesis and debate (for me at least ) I like carbon for several reasons

1) Increased durability
2) Increased penetration (some will disagree, but IME that is the case)
3) Better shaft recovery/stiffness for easier tuning from set-up to set-up
4) Flatter trajectory

As I’ve found over the past years #1 is not always a given with most IC carbons, since they wear out at a quicker rate.

Where I currently hunt a 30 to 35 yard shot is not out of the question in some cases. In my home state a 40 yard shot is quite common hunting crop field edges. It took one season of misjudging my yardage by 5 yards or so and barely shooting over the same very nice buck’s back both times with heavy, slower arrows (aluminum). First time I judged him for a tad over 30 and he was at about 25 yards, the second time I judged him for 40 to 41 and he was around 36. Both were good shots and I would have center punched his lungs had I got the yardage correct, instead I grazed his back (I’ll also not that both times he didn’t even jump the string. He was completely relaxed and due to the situation quite likely barely heard the bow).

With my current set-ups and the speed they produce the difference 5 yards makes is negligible, and I would have drilled that buck the first time.

Sure I can work on my range estimation, and have done so (at the time I was shooting 3D competitively), but in the heat of the moment hunting, I suck at judging yardage, plain and simple. I suck @ 3D too, but that' s another story for another time

I have nothing against aluminum, it precise, easy to work with and consistent, but until I can get a bow shooting it @ the same speeds I shoot carbon at now w/ the same draw length and poundage, and it becomes more durable, I’ll stick w/ A/C/Cs. They offer all the advantages of both shaft types with little if any disadvantage from either.
