I have some comments on this ball in the Track section of this site, but the new Track Kinetic is probably the hardest corning ball in the EBI lineup right now, and its a weaker piece, very fast responding cover to friction in my opinion. Seems to work best for me when using on a blended pattern.
the pigment in the colors is what gives this cover/ball, its reaction
certain colors are slower responding and others are the opposite
They don't have a "pearl" or "solid" additive
Its the chemistry of the pigments that determine this
