Aim for the arrows instead of the pins for better accuracy.  The arrows are located a ways out on the lane.  Rolling the ball over the arrows will take some foot adjustment at each arrow.  The adjustment should be to the right for the futherest arrow to the right.  Move slightly to the left for the next arrow going left toward the center and left again slightly for the next arrow to the left and etc.  There are also dots at the approach which may be used the same way as the arrows.
