To Layout the AMB properly, you must first mark the "Virtual Mass Bias" by drawing a line from the 1/4" locator pin on the backside, through the 1/2" Black flip pin around the ball. Mark an "x" 180 degrees from the AMB pin (13 1/2" from the AMB pin which puts the "x" 6 3/4" from the black pin. This Virtual Mass Bias point can then be treated using the same general rules that apply to other typical mass bias spots.
*** By using the AMB cap to create an Anti-Mass Bias (negative mass bias on the back side) it allows the ball to have a lower RG than the original DC core while maintaining a high differential. It also helps maintain more of the core dynamics for most drillings. In the case with most strong Mass bias balls, when drilling the thumb - you remove a large portion of the heavy core or cap used to create the bias, resulting in less of the core's original dynamics. BUT, with the AMB core, you drill into lighter coverstock and save almost all of the original core shape - retain
