The Storm Virtual Gravity was one of the most successful and best selling balls of all time, we just made it better. More aggressive. More strikes. The Storm Virtual Gravity NANO!
Storm is known for producing the best high performance balls on the market. When the Virtual Gravity was released in 2008, it not only turned heads but gave bowlers of all skill levels an unprecedented amount of hook on even the oiliest lanes imaginable. The new Virtual Gravity Nano is intended to create a similar yet stronger ball motion built specifically for heavy oil. This can be accomplished with either a stronger coverstock (texture) or more aggressive weight block (lower radius of gyration or increased differential). As the original Virtual Gravity quickly became Storm's all-time best seller, the new Nano is sure to follow in its footsteps...and yes, those are big shoes to fill! Looking at the original Virtual Gravity, the Shape-Lock HD weight block/core system produced a fast-revving action that especially helped bowlers looking for a stronger change of direction usually privy to only those with big rev rates! The Shape-Lock HD motor will continue to power the Nano as well. A breakthrough in coverstock technology rarely happens due to the complex nature of chemistry and polymer science. But Storm's research and development team is committed to maintaining the "pole position" in bowling innovation, so it's no surprise that we are changing the game yet again with the new NRG cover. With Nanotechnology, NRG will give bowlers increased oil traction due to the micro-dynamic enhancements of the surface. Just looking at the surface of the new NRG material shows you the increased surface texture between the peaks and valleys, as well as the more aggressive edges on the top of the peaks! We're continuing to push the envelope; we just hope you are ready for it.
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.
