I would never consider going back to aluminum. The only problem I have had with my carbons are snapping them off when I hit an animal. Carbons are either straight or broken there is no in between. I shoot the carbon 3D express and they are within .001, how much straighter can you get. I think where most guys run into trouble is shoot at a single spot target. You can ruin aluminum and carbons when they smack together. The aluminum will end up denting and the carbon will fracture. Alan
