First Impressions
The Brunswick Nirvana brings an extremely vivid Red, Blue and Green Solid look to the lane. Inside works the asymmetric Nirvana Ultra Low RG core, which shows a 2.477 RG, a massive 0.054 differential and a 0.013 intermediate differential. The cover is the ECS (Enhanced Composite Segmentation) Solid, brought to an extremely tacky texture out of the box with a 500 and 1500 Siaair finish. Thanks to the very low RG and the massive differential, the ball barely skids and instead bites into the lane extremely early. These specs should make the ball aim for an incredibly strong, heavy roll phase.
Comparison
Comparing the Brunswick Nirvana with the Brunswick Absolute Nirvana, the original model shows an extremely similar, hard-hitting reaction, with the cover setting the benchmark for midlane control. Against a ball like the Storm Alpha Crux, the Nirvana offers a very similar, strong and steady asymmetric hook thanks to its huge differential. When the transition changes the lane and friction increases, the heavy surface keeps the ball from jumping off the breakpoint uncontrollably, but it burns up considerably. It works very well on fresh boards.
On the Lanes
The Brunswick Nirvana is most at home on heavy lane conditions. It is an outstanding option if you're looking for a dependable and extremely strong ball motion. The asymmetric core creates an absolutely predictable, heavy motion, which builds confidence when playing direct lines in deep oil. The ball should secure carry through a consistent, powerful entry into the pocket. On dry patterns it inevitably burns up too much energy in the heads.
