The Track Logix was designed to skid through the front part of the lane then react big on the backend. This ball combines the QR-7 Pearl coverstock with the LT-2 core to create a versatile upper-mid performance ball that is easy to throw out to the dry and then it comes right back to the pocket on different oil patterns. The QR-7 Pearl coverstock provides length with backend angularity and continuation. The core of this ball, the LT-2, was designed to store energy for the backend. This ball works best when it is up against medium oil conditions.
