Aura™ Paranormal

Available February 6, 2013


The Optimum-Hook Solid coverstock is Brunswick’s newest development based off our performance enhancing additive chemistry research. Optimum-Hook Solid coverstock provides an overall hook potential higher than any Brunswick ball to date. The overall hook potential is increased by added traction in the mid-lane and backend. The new Optimum-Hook Solid coverstock incorporates a new base reactive along with our additive technology to create exceptional traction in oil for the Brunswick product line.


The Aura Ultra Low RG core features a single density rounded-off elliptical inner core. The core is dynamically designed to extend the rotational energy, boosting angular velocity to transfer energy to the pins for increased pin action and higher scores.


The Paranormal Aura continues a new age of ball motion for Brunswick never seen before. Exceptional hook potential, quick response to friction with strong continuation on the backend. The Paranormal Aura with its 2000 grit Siaair Micro Pad finish, reaches the highest hook potential of any previous Brunswick ball to date on medium to heavily oiled lane conditions.


The Paranormal Aura can be drilled using the standard drilling techniques developed for asymmetric bowling balls.


At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
