Storm is known for producing THE BEST high performance balls on the market. When the Virtual Gravity Nano was released earlier this year, it immediately became the number one selling high performance ball on the planet! Every lane in every bowling center around the world quickly turned orange.

Nanotechnology is the study of manipulating matter on an atomic and molecular scale. As we have mentioned before, a breakthrough in coverstock technology rarely happens due to the complex nature of chemistry and polymer science. But Storm's is all about innovation, so it's no surprise that the new NRG™ cover has again taken the world by storm. The magnification of the surface of the new NRG coverstock shows you the increased surface texture between the peaks and valleys, as well as the more aggressive edges on the top of the peaks! Thank you nanotechnology! Continuing to move forward with the new technology breakthrough, our new release will glide through the heads more easily than the original Virtual Gravity Nano yet still handle heavy oil.

The Shape-Lock HD™ Core which powered the original Virtual Gravity Nano produced a fast revving action that helped bowlers create more ball motion and total hook. While the new nanotech cover provided a lot of sizzle, unless it's paired with a quality weight block or core you will never see the advantages of either. In looking for different ways to expand the benefits of nanotechnology, we explored several
additive options to the base NRG coverstock and found that adding mica to this shell material created a cleaner glide through the heads without sacrificing any of its ability to handle larger amounts of oil. You'll see increased entry angle with the new Virtual Gravity Nano Pearl with simultaneous amplified oil traction usually reserved for textured solids.

Storm "Pro CG" Technology



PRO-CG: A Pro-CG is where the CG ends up a certain distance left or right of the Pin and PSA (preferred spin axis). If you draw a line from the PIN to the PSA on average the CG would need to be 2" or more from that line. That distance will vary depending on if the CG was to the right or left. Although still categorized as a first quality ball it has limited drill options (see our Pro-CG Drilling Options) that requires a certain type of layout. Please consult your pro shop professional before purchasing one of these balls.

How or why is a Pro-CG manufactured? A pro-cg is created during the manufacturing process. When the pin area is being drilled the core can slightly shift. When the weight block shifts just a small amount (1/16" - 1/32") it pulls the CG off the Y axis towards the Z axis. This is why on some balls you will notice the CG is a far distance away from the Pin to PSA line. These small shifts do not affect the reaction or quality of the product, but it can limit the drilling options. Therefore we offer a different set of drilling instructions and mark them as Pro CG's.

How much does the CG matter? The CG is the least of your worries when trying to match up a bowling ball to a bowler for their desired reaction. To learn more about how the CG's relevance and other factors when determining ball reaction, see our chart below provided by the U.S.B.C. Please also visit www.bowl.com and read some of their more recent articles on ball motion studies. (The U.S.B.C. is an independent organization with a common goal to protect the sport of bowling). This ball is sanctioned for use during USBC competition.
