What kind of shooting are you doing? I find that carbons are tougher in the woods and take abuse that would bend and dent or kink aluminums. However, I've also had the nock end split when I hit the steel bar in a 3D target leg. If you're shooting field archery, aluminums should last but as mentioned, the jazz arrows are a softer alloy. What is your draw length? This will play a big part in your arrow selection. For example I'm shooting a 45lb recurve with .400 spine carbons, but they're full length and my draw is 30.75".
I still get wrapped up in arrow cost once in a while, until I remember that going to one highpower rifle match costs me more than a dozen arrows!
