Definition
A hole in the ball that is not used for gripping purposes and is not considered a vent hole.
Flare Increasing Extra Hole
A flare increasing extra hole is located past the positive axis point on a line parallel to the midline (Figure 2 numbered location 1).
This location of the extra hole offers and increase in mid-lane, backend reaction and flare.
The further away the extra hole gets from the positive axis point at a limit of 3 3/8", the greater the influence on reaction.
Another location for a reaction enhancing extra hole is below the positive axis point (PAP) on the vertical axis line(Figure 2 numbered location 2). Reaction is enhanced on this line in the midlane, but backend is diminished compared to the hole past the PAP on a line parallel to the midline.
Flare Decreasing Extra Hole
A flare decreasing extra hole is located on a line parallel to the midline before the positive axis point.
Flare. midlane and backend reaction are diminished with this extra hole location (Figure 2 numbered location 3).
Another location for a reaction reducing extra hole is above the positive axis point on the VAL (Figure 2 numbered location 4). An extra hole placed on this plane offers the least track flare, midlane and backend reaction. The further away the extra hole gets from the positive axis point at a limit of 3 3/8", the greater the influence on reaction.
