Mo Pinel says they now call them Additives. Some of his pearls seem to be smoother off the break which particles were compared to their competitors.
One of the best of his new balls I have seen is the Squatch pearl,
Also, the ball is drilled with a special pin down drilling I call the LuckyL !
Awesome powerful and smooth!
Sincerely,

PS I have an AMF Radar Alert aroung. Still pretty nice for that Pearl Particle smooth move!
