Yes, The cause of most of the left tear issued have been idler lean. Mine was leaning right causing my string to track right. This caused my left tear. I have had bullet holes since the adjustment to the left cable yoke. I do feel the Switchback is a little more sensitive to torque than the other Mathews. This is my 5th Mathews bow, and it is definetly the most sensitive to tune, but it shoots so well that it is worth the extra tuning. Very smooth, quiet, and vibration free bow, and pretty quick too!
