The standard unit hosts an external pad on the sole that positions the center-of-gravity (COG) law and farther back for higher trajectories and increased distance. The draw unit, on the other hand, features the pad farther back and closer to the heel to promote easier club rotation. In general, testers say the G15 is highly responsive, the G15 provides consistent performance, and the G15 launches shots high. However, some people a big more freedom to work the ball left or right.
