RE: I know the carbon vs. aluminum issue has been beaten to death..but
Opinions are like, well you know what their like...anyway, you have to buy the high end carbons to get the straightness of aluminum. I currently have a dozen aluminum and about 3 dozen carbons. Aluminum are by far the straightest of the two and yes they are heavier and a little slower. Heavier means better KE and quieter, but they are slower. I don't get crazy with the speed thing since the fastest bow is still way under the speed of sound. Speed is fine, accuracey is final.
