Ive been tossing around the idea of picking up a stereo matrix, however, after watching videos and looking at pictures online, I've noticed that there are two different types of stereo matrixes. The only difference between them is that one has a functional perc in-between the two matrix percs. i attached some pictures to show you guys what I'm talking about. Has anyone hit both? How do they compare in smoothness and drag? Or if anyone owns either piece please feel free to chime in. Im not quite sure which version ill end up getting but I'm leaning towards the one with the perc in the middle, help me decide!
