It is a strong, high-flare ball with an aggressive, angular backend. The listed flare potential is 4 to 5 inches, and the symmetric Rocker AI Core measures a strong .050 differential at 15 pounds for heavy flare and a powerful but readable motion. The polished NanoStar Pearl pushes cleanly through the heads, then makes a sharp, aggressive move when it reaches the friction, later and more angular than the solid Rockstar.
