What is Pin-In/Pin-Out?

Bowling Tips
A bowling ball drilling term that is relative to a bowler's track, design purposely for creating more ball dynamics.
Pin: A dye mark on the surface of the ball that indicates the position of the top of the core (the position of the weight block inside the ball).
Pin-In: This is a ball that was manufactured with the pin and the center of gravity within 1-1/2" of one another. Center of gravity is the heaviest part of a ball. The CG can be found by looking for a dye mark placed on the ball by the manufacturer marking the center of the weight mass relative to the top of the ball. A Pin-In ball is an excellent choice for control and less hook.
Pin-Out: This is a ball that was manufactured with the pin and the center of gravity distance greater than 1-1/2" from one another. A Pin-Out ball can usually be made to hook more and flip more dramaticlly than a Pin-In ball. Will also give the ball driller more options.
