Value and Performance have always been synonymous with the Roto Grip brand, and the all new Dark Star stands to continue that tradition.
Our first goal was to develop a stronger Shield Line ball to fit into the Roto Grip line. The team felt that there was too big of a gap between the Nomads and the Planet series balls. The intent was to create more mid-lane read with stronger backend motion, so we developed the Photon Core with a lower RG value and a higher differential.
To enhance this core motion we also added the Ultimate Vision pearl coverstock to this ball. This performance proven coverstock found on the Epic and Illusion series of balls. It boasts a higher coefficient of friction and surface texture for added traction in the oil and superior backend performance.
This combination of core and coverstock was the ideal fit into the line. Our tests showed that it filled the gap between the Nomads and the Planet series balls perfectly.
The Roto Grip shield line has always been known for amazing performance for affordable prices, and this time they’ve raised the bar without raising the price! The Roto Grip Dark Star is currently selling for $79.99 and is rated at a 168.4 on the bowlingball.com Perfect Scale®!
At Roto Grip we pride ourselves in providing a complete line of bowling balls in both value and performance.
The recent introduction of the Dark Star created a nice compliment for those medium to drier patterns, but we still needed a strong solid reactive in the Shield Line for those patterns with a bit more volume up front.
The Riot is just what the kingdom ordered. The utilization of the Ultimate Vision solid reactive coverstock is the key to this addition. The increased surface topography and greater coefficient of friction battles those medium to heavier volume patterns with fierce intensity.
The Photon core delivers the energy behind the Riot. This newly designed medium RG (2.58) and medium differential (.040) core creates greater mid-lane read and increased entry angle to the pocket than its predecessors in the Planet series.
It's time to start your Riot in the Bowling Kingdom!
Roto Grip continues to add necessary pieces to their arsenal, and as always with the Shield line you’re getting unbelievable performance at an amazing price. The Roto Grip Riot is currently selling for $92.99 and is rated at a 170.5 on the bowlingball.com Perfect Scale®!
Brunswick started the attack with the Brunswick Siege, and now they’re really bringing the pain with the new Brunswick Evil Siege. The Siege attacked the oil up front. If you need something to get through that first line of defense and make it’s attack move down the lane, the Brunswick Evil Siege is the perfect weapon!
The Evil Siege is the second in our new series of Pro Performance balls and features the new MACE asymmetrical core as well as the new solid Propel Pearl coverstock. This is a strong ball that battles medium to heavy oil and responds quickly to friction for great pin action.
The Brunswick C (System)2.5 changed the way we look at the chemistry of bowlingball coverstocks. Whether sanded or polished the molecules stayed the same, which was a huge breakthrough in technology. Well now, the Brunswick C (System)3.5 carries on that legacy, but this time with more overall hook and an earlier roll for heavier lane conditions.
Chemical Friction Technology – Developed with Carmen Salvino, the Brunswick C (System)3.5 is the next evolution in Chemical Friction Technology.
Let the science of friction improve your game!
CFT 3.5 is the next evolution in Chemical Friction Technology. The CFT 3.5 coverstock has a higher friction factor than the original CFT 2.5, which quickens response time, improves down lane traction and increases the overall hook.
The new I-Block core was engineered specifically for the CFT 2.5 coverstock to create maximum forgiveness, strong entry angels along with versatile drilling layouts.
Ball Motion – With its 4000-grit micro pad finish, the Brunswick C (System)3.5 offers a higher friction factor and increased response time to friction alternative than the original C(System) 2.5. The new C(System)3.5 is best used on medium-oily to oily lane conditions when a quicker response motion is needed to increase entry angle to the pocket.
