The Storm Axiom Pearl continues the line of statement bowling balls. This ball uses the same Orbital Core as the original solid version and the NeX (Nano Extreme) Pearl coverstock which is an upgrade to the NRG coverstock. The NeX Pearl reads the midlane and produces an impressive backend. The Orbital Core doesn't require much from the bowler to get it reved up early. This ball matches up best on medium to heavy oiled lanes.
