Designed with the extreme oil patterns in mind, the Centaur-AMB Particle will chew through the oil like it's not even there. Using the high flaring AMB core design in combination with our new high load particle coverstock, this ball will hook when nothing else will. If you are in need of a heavy oil ball, than look no further. You will not find more raw power in a ball anywhere.





"This steel blue ball hooks a bunch, and oil won't be enough to stop it's punching power." Mike Riggins - Bowlers Journal International





"This is one of the earliest rolling, and biggest hooking balls I have ever thrown. Bowlers who run into extremely heavy oils, or those with very little hand will love this ball." Rich Hanson - Bowling This Month

The Centaur-AMB Particle uses the same large differential, high flaring dynamic core as the Antique Bronze AMB but encases it with an extremely aggressive high load particle coverstock.

The AMB Particle generates an extreme amount of traction on the lanes and therefore will roll sooner and not have the backend snap like the Bronze AMB. This ball is designed for oil, Oil, OIL !!

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 - retaining the true reaction originally designed by the core. ***
