Other popular Storm and Roto Grip bowling balls that have been discontinued include:

#4 Storm All Road Bowling Ball

Possible replacement the IQ Nano Pearl Bowling Ball.

Testing is a long process that involves a lot of people and first-rate technology but most importantly, it begins and ends with the bowler. Nanotechnology: Why is something so small so big? Our NRG material deals with the smallest of the small. In fact, it is the manipulation of matter at the molecular level. In bowling ball tech, you can’t see what’s there, but you can certainly feel it every shot you make. There’s an abundance of enhanced traction when our proprietary Nano additive is mixed with our coverstocks. Materials reduced to the nanoscale can show different properties compared to what they exhibit on the macroscale. NRG Hybrid is unique unto itself. The coefficient of restitution is the ratio of the final to initial relative velocity between two objects after they collide. Why is this important to the bowler? Well, simply put, when a ball has to contend.

#5 Roto Grip Wild Streak Bowling Ball

This was a unique core and cover combo so no current balls would be close in ball motion in my honest opinion.

Creating the Mutated Rotary™ weight block was a long time coming. After countless request to re-introduce weight blocks of the past, it was time to configure a new higher RG symmetrical shape in order to produce more length and more down lane shape in the HP3 line.

#6 Roto Grip Hustle 3TP Bowling Ball

Possible replacements: Hustle RAP

Inside you will find the now famous Hustle™ Core which measures in at more of a medium rg number. Not too high and not too low, it measures in just right. While the core differential measures in at a lower value for more control down lane.

The VTC-P18™ Pearl Reactive cover was first used on the Winner™ and instantly became a fan favorite. This formula of pearl increases traction throughout the lane while still retaining enough energy to respond down lane.

Created with versatility and reaction in mind, the Hustle 3TP does not disappoint. Compared to the rest of the line of Hustle’s, the Hustle 3TP just like the Hustle Au will provide the most length with more backend reaction due to the pearl cover.

#7 Roto Grip Hustle HSB Bowling Ball

Possible replacements: Electrify Hybrid

Inside you will find the now famous Hustle™ Core which measures in at more of a medium rg number. Not too high and not too low, it measures in just right. While the core differential measures in at a lower value for more control down lane.

Wrapped with the proven VTC-H18™ Hybrid Reactive coverstock, you will notice that even though this ball comes out of box factory shined, it will still provide plenty of traction and down lane reaction.

Ideal for those Lighter to Medium Oil conditions due to the dynamic combination of core and hybrid cover at a cost friendly price. Compared to the rest of the line, this ball will be a little longer than the Hustle INK, but not as long as the Hustle 3TP or Hustle Au. 

#8 Roto Grip MVP Pearl Bowling Ball

Possible Replacements: Electrify Pearl, Hustle RAP 

Core: First used in the original MVP, the Neutron NXT Core has quickly gained credibility by all who have tossed it. With the higher RG value and medium diff, this core produces plently of length and plenty down lane motion no matter your bowling style.

Cover:The newest Versatile Traction Control Pearl cover, better known as the VTC-P19 Pearl Reactive Coverstock, takes a step forward in terms of durability and performance. Just know it will provide more responsiveness down lane than the VTC-H19 Hybrid cover found on the original MVP.

Condition: This ball was designed to excel on those lighter oil patterns as well as those patterns that have transitioned after af ew games when the front of the lane starts to hook early. There is no doubt this ball wil be an ideal “go to” ball when your bigger balls start to get lazy down lane. Between the core and the cover, this ball will provide plenty of shape down lane when you need it!
