i have the maxxis 31 and i think its a really good bow . i dont personally know about the carbon matrix , i have not shot one . but as far as the maxxis it has a good smooth draw and no vibration at all and its fast and hits hard . as far as the one for you it all comes down to wich on feels better to you and how much you want to pay . if the matrix feels the best to you and you have the money then thats the one you should go with . and the same thing if the maxxis feels better . everyone has different thoughts on what they want in a bow . but what it really comes down to is what you want in a bow , so i would say go shoot them both .
