Something out of this world is coming from Motiv Bowling. The all-new NEBULA is built for one thing: maximum angle through the pins. This isn't a minor incremental improvement, this is a ball that's not even in the same universe! We've reached new heights in down-lane motion by combining two brand-new technologies: the Hadron Core and the Dark Matter Propulsion coverstock. This Cosmic Black Nebula is cleaner in the front, sharper in the back, and more explosive through the pins. At the center of the Nebula is the brand-new Hadron Core—our first dual-density core in over 8 years. This new symmetrical core was worth the wait, generating incredible energy retention for an explosive backend motion. This new addition is intended to be the most versatile dual density core in the Motiv line while still providing the trademark dual density flip down lane. And the high-density star block at the bottom of the core fuels explosive reaction to new levels! Wrapped around the Nebula is new Dark Matter Propulsion Pearl - the sharpest, cleanest, and most angular coverstock MOTIV has EVER created. Every single adjustment to Propulsion tech was made with one outcome in mind: faster backend reaction. Even the cosmic-black color choice and pearl additive were made solely to maximize angularity. As a result, the Dark Matter Propulsion cover is cleaner and more reactive than any Propulsion technology prior. This cover is pure rocket fuel.
