Tried them about a year 1/2 ago and found A/C/C's much more durable . The Matrix has a thicker aluminum wall(for weight) and 2 wraps of carbon , the A/C/C has a thinner wall,but 3 wraps of carbon. I had trouble with the Matrix bending relatively easy . After about two weeks I was down to 6 out of dz. I gave those 6 away and went back to A/C/C 'S at the time .I heard later that several people had complained about the same thing at the local archery shop.The A/C/C's weigh a little less but in a 3-60 you should be able to obtain 400 grains pretty easy depending on your set up.

I don't know if they have improved the Matrix since then ? Hope that helps ?!
