One good thing about aluminum that nobody has mentioned yet... There is only ONE major manufacturer of aluminum arrows. There are a TON of outfits pumping out carbon arrows and not a single shop in the country carries more than a few different brands. The 2315 XX75 Camo you buy in Florida will be the exact same 2315 XX75 Camo you'll find in Oregon.

Think of this scenario. You're set up with, say, Carbon Express arrows, fly to a hunt in, maybe, Alaska and find out the airline lost your arrow box. You find out that there's not a single place to buy Carbon Express arrows within 500 miles of where you're hunting. You have to buy a different brand which has different shooting characteristics. So, you get to spend a day of your hunt retuning and resighting your bow to the different arrows.

On the other hand, if you're set up with 2315's and your arrows get lost, you simply walk in the store and buy another set of 2315's identical to the ones you're tuned up and sighted in for.
