The original Invasion's Origin core produced a fast-revving action that helped bowlers optimize their ball reaction without being over-reactive. It is strong and steady for bowlers of all styles.
For the coverstock, we will utilize nanotechnology in the popular and proven R3X base reactive material. Nanotechnology will increase the performance due to its added surface topography. Combined with the pearl additive which improves backend reaction, these added peaks and valleys create more aggressive edges to help dig through the oil pattern and increase traction to the lane. If you want hook you've got it here! In fact, testing showed an increased entry angle and backend reaction created with this pearl additive.
The 1500-grit polished finish allows this ball to clear the heads without sacrificing any midlane roll. With nanotechnology, this new release allows you to open up the shoulders and attack the break point with confidence. If you liked the motion of the Invasion Nano you're sure to love the pearl version even that much better. It all about the NANO!
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.
