A/C/C's have a thinner walled aluminum core tube and 3 wraps of carbon ! They are slightly lighter weight but stonger and more consistant with the 3 wraps of carbon !

The Matrix on the other hand have a thicker aluminum core tube(giving them a little more weight)......but only 2 wraps of carbon ! Therefore they are easier to bend !

I didn't think the Matrix were even in the ballpark ........durability wise........when I tried them compared to A/C/C's !! JMHO !
