Carl told me to put a 4 x 3 1/2(pin under ring) drill on mine, got it drilled up with that pattern and i can tell you this ball moves, and mine isnt a strong arc, its more of a snap on the backends and its one hell of a snap, ive never been able to stand far left and throw the ball out to the 3-5 board and have it come back but i can easily with this ball, hell it goes brooklyn half the time
and scoot, the box finish says TCS 4000
