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!

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 Duo is a little earlier than my typical goto pearls but it offers me a more controllable motion downlane than most pearls do for me. I tend to enjoy this one a bit more on sport patterns than house shots but the Microtrax Pearl Cover on the Mentor Core definitely offers a different look in the bag. It could be very valuable at times.

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.

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
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!

Likes: 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!

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.

Roto Grip Duo - Pallet Ball

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.
