RG Duo

The Roto Grip Duo Latest addition to the HP3 line RG 2.49 diff .046 Mentor Core MicroTrax Pearl Cover The Duo is so much more versatile than I expected. When I ready the Core #'s and saw the cover, I assumed this would be a very forward rolling ball. It has proven me wrong and can be used by many different styles on many different patterns. I can get left and swing it or stay straight and work its forward roll. I have seen the Duo skid for others that usually need help getting the ball down the lane. It's not going to be a hockey-stick skid/flip but also not early and flat. This is one that should be very common at leagues, with many different styles benefitting from it's versatility.

Roto Grip DUO!

Ball Specs: Ball - Duo Core - Mentor Coverstock - MicroTrax Pearl Surface Finish - Reacta Gloss Finish VLS Layout - 4.25x4x2 Bowler Specs: Right Hand 14 - 15 out of hand Tweener Speed/Revs matched PAP: 5 ⅜ over x ⅞ up Lane Condition: THS Review: A strong pearl symmetrical, something that you cannot really go wrong with. We have the 900 Global Zen, Storm Fate, and Idol Cosmos (discontinued recently). Adding the DUO to the line was an awesome move. I won;t sugar coat this. This ball is NUTS. Think about it, you have the Mentor core, which provides strong flare and hitting power, and the same coverstock that is on the Exotic Gem!!! One of the strongest coverstocks in the industry, and we have it on the Roto Grip DUO. The ball hits like a truck. You can watch any ball review, watch any pro throw it, and you will see this ball bury the pins. The help from the microtrax coverstock is insane. When I heard that this ball had that coverstock on it, it was going to be an immediate buy and I was going to recommend it to my friends. The DUO provides a clean transition through the fronts and midlane, but it really like to start revving up once it gets closer and closer to the dry. Some of the weaker balls we have in the SPI line like to miss skid just a tad further, so taking layout into consideration is extremely important. Whether we played right, or jumped in left, the DUO responded well to both. From what I saw, this ball shined well playing just inside of the 2nd arrow mark. Bowling on THS, it would hold the line to the pocket if I missed in and was forgiving if I missed right. The strength of the DUO swished around pins like it was nothing and corner pins were not an issue as long as the entry angle into the pocket was not flat. I am extremely impressed with this piece and I hope we get another year out of the ball! Mitchel G. - YT: Fullsendbowling

Duo - Please send me a pallet

About Me 900 Global Staff Left Handed: High Rev High Speed Player Pap: - 47/8 +1 Rev Rate: +-500 Speed 17 mph Layout: 70 X 3¾ X 30 Ball Video: N/A The Roto Grip Duo is what I like to call a “Pallet Ball.” What I mean by this is that I would love to buy a pallet of them and keep drilling this ball up. The Duo is so clean and controllable from the front part of the lane to the backend. Speaking of the backend, it is so predictable with incredible finishing power. The amount of mistake area that I can create with this ball is ridiculous. This ball is going to be a benchmark ball for me and will be the first ball out of back on any pattern I throw with. The Duo has been able to replace quite a few balls in my arsenal because of the versatility I have in throwing this. It would be in your best interest to get a Duo and put one in your bag, not only will you bowl well with it but 5% is going to go to charity. One of the best balls I have ever thrown and that is saying quite a bit.

Roto Grip DUO

I am a higher speed, rev challenged 220-250ish, high tilt, high rotation, and super low track player, I drilled my Roto Grip DUO 5x 3 1/2 x 1 3/4 using the Storm VLS and my axis point is 3 ¼ right and 7/8 up. The Roto Grip DUO is middle of the road pearl symmetric benchmark ball that is easy through the front of the lane with great continuation down lane without being too angular. Overall, the ball is responsive and I see myself using this on house shots or medium volume patterns. My YouTube video of the ball can be found at: https://youtu.be/o2Us3qgPE_c?si=gkKKb7ZaI36xwHeV

Awesome ball for an Awesome cause!

As soon as I saw one picture of this ball I knew we were in for a good one! First and foremost it is an amazing thing the see Roto Grip and Shefanie teaming up for such a great cause like Big Brothers Big Sisters and donating money from every Duo that they sell! My home center every year puts on a big weekend event for Big Brothers Big Sisters so this definitely hit close to home for me. Now for the ball itself, my first time throwing it was for my reaction video and to say that I loved what I saw would be an understatement! The Duo definitely has given me some good old classic Roto Grip vibes! If you were a fan of the Wrecker or the Uproar then you should absolutely look into getting yourself a Duo because I personally think it shapes up exactly like those 2 balls did. It is definitely a tick stronger tho. It is also a perfect 1-2 punch for me with the Exotic Gem. Very similar shape wise except the Duo is a smidge weaker and a perfect ball down for when the Exotic is starting to lock up. Honestly tho if you haven’t drilled one yet then what are you waiting for!

Roto Grip Duo review by Chris Pollentier

Roto Grip Duo Coverstock: MicroTrax Pearl Reactive Box Finish: Reacta Gloss Core: Mentor Core RG: 2.49, Diff: 0.046 (15 lbs) VLS Layout: 4 3/4 x 4 x 2 1/2 Dual Angle Layout: 45 x 4 3/4 x 40 PAP: 5 3/16” right x 5/8” up Rev rate: 400 rpm Average speed: 16.5 mph Location: Prairie Lanes, Sun Prairie, WI Pattern: Medium volume THS The Roto Grip Duo is the recent addition to the HP3 line that features the MicroTrax Pearl Reactive cover, same as on the Exotic Gem, and Mentor symmetric core that was partly inspired by the Dare Devil line of balls from a few years ago. All that goodness aside, what really makes this ball special is that it’s the first collaboration between “The Shafanie Duo” of PWBA stars Stephanie Johnson and Shannon O’Keeke, and is in support of a partnership with Big Brothers Big Sisters – with 5% of the sales from the Roto Grip Duo being donated to aid in the development and support of kiddos within the program!! This ball is a performer on the lanes as well. Because it has the same cover as the Exotic Gem, the Duo feels very much like a symmetrical version of the Exotic. The combination of the low RG, mid-differential core and strong coverstock makes this a strong but predictable pearl ball. Because the Duo comes out-of-box with the Reacta Gloss finish, I scuffed the surface lightly with a used 2000-grit Abralon pad like I have with many other balls that come polished just to scratch the surface a bit and knock some shine off. The Duo has thus far proven itself to be very versatile and I believe would be a great ball for most any league bowler as well. The Duo is clean enough to get through the front part of the lane to remain online, and it has a good strong backend reaction that isn’t so sharp that you can’t control it. In most cases, the Duo is the first ball out of my bag; and for league night it’s the only ball I need. If you’re looking for a ball that is cleaner with less overall hook than the Gem or Exotic Gem, but still something stronger than the Hyped and is versatile enough to thrown as the lanes transition – the Duo is it!

Roto Grip Duo

Layout: 50 x 4 ½ x 35 The Duo has about as strong of a late midlane/backend reaction as you can have without it being classified as “skid flip”. The decent amount of midlane read that the Duo has both allows it to have a modicum of predictability and arciness, but overall, this thing can really fly in the back part of the lane! It has become my favorite ball for when strong backend is needed, especially on house shots. I've paired the Duo with the Summit to be a killer combination – the Summit shines on fresh or heavier oil, and the Duo comes out when the Summit starts to pick up too early or when I need to circle the lane more. The bright green and black color combo on this ball is really nice, also.

Roto Grip Duo review by Mike Craig

I drilled up my Duo 5 x 4 x 3. This is my favorite layout for first out of the bag pearl balls. I hit the surface with a light 2000 to crack the shine and smooth the reaction out. I put the DUO up against the SUMMIT and pin under EXOTIC GEM. Just like you would expect, the DUO is dead in the middle of these two. A little later than the SUMMIT and quicker than the pin under EXOTIC. The DUO was at home for me on a middle pattern and flared around 4-5". I feel that the DUO will get play as a first ball out of the bag at places with some early friction burn in the fronts and also when the big solids are starting to lock up and lay flat down lane.

Duo

The new Roto Grip Duo is the result of a partnership with Big Brothers, Big Sisters. A portion of all sales of the Duo will go to this charity. The Duo features the Mentor core wrapped in the MicroTrax pearl reactive coverstock. The RG at 15lbs is 2.49 and the differential is .046. Drilled at 5x4x2 (pin above the bridge) the Duo reminds me of the original DareDevil, only smoother. The Reacta Gloss finish of the Duo provides effortless length through the front part of the lane and a very strong but predictable backend motion. For a pearl coverstock, this ball does not have that hockey stick shape backend but a much more arcing motion usually found in solid cover stocks. This allows the Duo to be a great choice on the tougher patterns when control is priority number one. The Duo won’t wow you with big backend hook or even overall hook, but it will control the pocket for you and provide excellent pin action. Get a great ball and help a great charity!!

The Baby Exotic Gem

Sam C.-Roto Grip Amateur Staffer High Speed-High Rev Layout: 60×5 1/4″x40 The Baby Exotic Gem. With this ball having the same cover stock as the Exotic Gem it has no problem hooking with that being said it needs some oil. Not to mention the colors of this ball just look sweet going down the lane. This pearl ball is strong in the oil and does not go wild on the back end. I would describe the shape as more of an aggressive yet controllable arc. Comparing it to the 900 Global Zen they have similar hook potential. The difference between the two I feel is the Duo with the medium strength core “floats” or does not rev up as early when it sees the friction. To me this ball is a step down from the stronger balls like the Gem or Exotic Gem but a step up from a Storm Revenant or Absolute. Not to mention this ball supports a great cause Big Brothers and Big Sisters!

Roto Grip Duo Review

The Roto Grip Duo was anticipated as a Zen like replacement ball, and while I feel like we get close to that but it is definitely something different. For me the Duo is still one of my cleaner options but on the stronger side of that spectrum being that it has MicroTrax Pearl on it, one of Roto Grip’s stronger pearl covers. My Duo has been a great option at home on the house shot but starts to struggle more when I have to get super steep with my angles. A touch earlier for me than a Zen, it becomes more forward at the end of the lane, and that’s where it struggles to create those steep angles. Otherwise a great ball for the majority of league night for me! And don’t forget, 5% of the sales of this ball go towards big brothers and big sisters of America!!!

Roto Grip Duo Ball Review by PJ Haggerty

The new Duo made by Roto Grip is the latest addition to the HP3 line and it’s impressive. With flashy, bright green shelf appeal, this ball also packs a punch. With an RG of 2.49 and a differential of .046, the Duo can be used by all types of players and on many different conditions. The Mentor Core is an upgrade from the old DareDevil that was made from Roto Grip years ago. The brains in Utah added a puck on the bottom of the core to enhance the motion down lane, and it definitely does that! I’ve drilled one Duo so far and really like it. I mapped it out as 5 1/4 x 4 1/2 x 2. This puts the pin above my bridge with a slight shift of the CG. It’s been a perfect compliment to my Gem, Exotic Gem, and TNT. Once those balls have done their job and I need something to get through the front but still dig, change direction, and still run over the 8-pin, the Duo is the ball I use. In most situations, I’m sliding left of 25 and curving it a good amount because that’s where I’ve seen the most success, but I’ve also seen the straighter players with lower rev rates use it to play farther right away from the traffic. If you need a ball that packs a punch, looks great going down lane, and can be usable for all types of styles and rev-rates, the Roto Grip Duo should be the next ball you drill.

What a beauty!

This ball reminds me of the Zen with its shape, heavy rolling and not very quick to change shape down lane. I still find the zen to be a touch stronger but this would be a great transition ball! I can see my self using this at our center late game one into game two!

Roto Grip Duo

The Roto Grip Duo is the new ball in the HP3 line. Duo features the new low RG symmetric Mentor core. Which is wrapped with the MicroTrax Pearl cover, which is the same coverstock as the Exotic Gem. I drilled mine with a 4.5x4x2 layout. I tested the Duo on an 20+ year old Brunswick Pro Anvil lanes, on house shot and a couple medium patterns. The Duo gets through the fronts pretty good and has a lot midlane rolly shape for me and can get a little forward at times if there isn't enough oil. I can see me using the Duo on the fresh to blend out the backends. Plus I can use the Duo on the short patterns like Cheetah, to control the overall shape of the pattern. I think Duo is going to be good for the average league bowler as it can handle the miss lefts in the puddle and the miss rights to the dry and it doesn't over bounce. Duo is a good ball down from the Gem's or reality. Cleaner than a Phaze 2 or TNT. Overall the Duo is a strong symmetrical pearl that can be used by a variety of bowlers! Plus a percentage of domestic sales goes to Big Brother’s and Big Sisters. Thanks for Stephanie Johnson and Shannon O'Keefe! for the support of the Duo!

DUO!

The Duo features the Mentor core wrapped in the Micro Trax pearl. The Mentor core is a lower RG and medium differential core. The Micro Trax cover has most recently been featured on the Exotic Gem. This combo provides a perfect cleaner option that will fit right below your bigger symmetrical options and right above your Electrifys and IQ’s. 5% of all sales are also being donated to BBBS, so what’s not to love??

Why Trust Verified Reviews?

Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.

Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.

As a consumer, here's how you can tell the difference:

Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.

Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.

So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
