      The AMB-IMMORTAL core has a heavy cap added to the bottom of the core.  This allows the density of the top cap to be increased significantly.  The result is a core that produces an extreme flare potential with it's 0.078" differential.


* (This ball was grandfathered in before the USBC changes and is currently higher than any new ball can be produced - BUT it is legal for use in all USBC competition because of when it was approved ). 


..... the IMMORTAL line:

     The IMMORTAL is the latest adaptation of our highly successful Anti-Mass Bias core design.  Unlike other balls which use dense materials to create a mass bias, the AMB design utilizes an extremely light cap opposite the desired mass bias location.  This AMB flip cap creates a negative mass bias on the side with the cap and also creates a positive mass bias at the desired location. This allows the bowler to drill the ball in just about any possible manner, without affecting the core shape or dynamics.  Due to the extremely high differential, this ball flares a ton which creates an earlier and harder arc reaction compared to other balls with similar covers. The IMMORTALs add grab and roll and can create a strong move for those styles needing help to get the ball rolling -but may burn up for bowlers without much speed or side rotation. 

.....theBlack Pearl IMMORTAL - Pearl:

     The Immortal Pearl will go longer than the Solid and flip sharper on the backend (still not a true skid/snap reaction).  Even though the cover on the Immortal Pearl is more of a skid/flip style reactive, the high differential causes it to get into an earlier roll in the oil than typical pearl reactives resulting in better handling on carrydown and less erratic snap on the back.



To Layout the AMB-IMMORTAL 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" white flip pin around the ball. Mark an "x" 180 degrees from the AMB pin (13 1/2" from the AMB pin whichputs 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 coreshape - retaining the true reaction originally designed by the core. **
