I prefer the 12" barrel. It puts more of the bats mass away from the knob and even mild end loads, seem to carry more bat speed through impact. Also, at least to me, because there is a shorter surface there is less deflection on impact with the ball, increasing the durability of the bat a bit. If you can find the sweet spot consistently. You can get greater distance out of the 12" than the 13".
