CORE TECHNOLOGY: Morph-Wing™ Core... The Morph-Wing Core is a dynamic asymmetric masterpiece that transforms unlike any other asymmetric shape when drilled. Mass displacement when drilling into the wing changes the core numbers more than any other asymmetric part on the market today thus providing a completely different flare pattern and motion based on the transformation of the core shape.
 
COVER TECHNOLOGY: V-R1™ Solid Reactive... The Versatile Response Solid material provides the most balanced and reliable traction-to-reaction ratio of any of our nano-free materials to date.
 
PERFORMANCE SYNOPSIS: Without a doubt the TRANSFORMER has the most transformable and tunable hook potential and breakpoint shape on the market today thanks to its unique core design making it super easy to add a specific motion to any arsenal.

  • Transforming The Game

    For the Transform Pearl, I decided to drill into the wing which I didn’t do on the original Transformer. The one main thing I have noticed with mine compared to some others is drilling into the wing gives this ball a really smooth shape with a good amount of length. I have been able to use this ball when the outsides are really dry. The ball is still able to get down the lane with a good amount of movement through the pins. Now for some of my customers that I didn’t drill into the wing, this ball has a ton of backend motion compared to most asymmetrical pearls out there. These balls have a different dynamic to them and really do give the pro shop operators a handful of options for their customers.

  • Great pearl benchmark

    Posted by Mike Walker on Jul 18th 2026

    Right Hand - 15.5 mph down lane, 335 +/-, PAP 4.75, 1/2 up. House shot at Bowlero Edmond. Layout 5x4x2 Roto Grip is once again featuring the innovative Morph-Wing with the asymmetric core but with a Pearl Reactive coverstock with nano-particles. This ball has a combination of customization, versatility, and continuation. The Transform rolled great on the medium/heavy fresh house shot. The layout allowed me the drilling to miss the Morph-Wing. However, you can drill this ball to your favorite layouts and it will work absolutely fine! Also, the colorway is on fire and looks like it on fore going downtown the lane! I feel this ball is best for bowlers looking for strong benchmark pearl and a ball for the competitive tournament bowlers that are looking for a something when the lanes begin to transition. I did roll this on a sport shot and I noticed this ball blended the wet/dry without sacrificing any recovery. The only downside I could see was that this ball may be too strong for lighter oil conditions and slower speeds. Overall, the tunable core is back! The length is clean and dependable on the latter part of the midlane and then it continues driving through the deck. This will be a go to ball once stronger solids begin to flatten and lose energy.

  • Favorite Asymmetrical Pearl

    Posted by Isaiah Ailstock on Jul 18th 2026

    The Roto Grip Transform Pearl drilled 4 x 5 x 1.75 has been an outstanding strong asymmetrical pearl that fits perfectly once I need more angle without sacrificing control. This layout gives me a clean look through the front with a strong, continuous motion downlane that never quits, making it easy to open up the lane and trust it to recover. The combination of the Morph-Wing core and MicroTrax Pearl cover creates a powerful yet predictable shape that handles transition exceptionally well. Overall, it's one of my go-to balls when I need strong backend continuation, excellent pin carry, and confidence that the ball will finish through the pins.

  • TRANFORM YOUR GAME

    The Transform Pearl is amazing. This ball allows me to open up the lane even on the fresh. It goes through the pins so effortlessly. I am very impressed with how this one rolls. It’s good on the average league house shot and gets the playing time on the sport conditions too. With a stronger core, this ball doesn’t stop enough the pins. Transform your game and get one today.

    TESTING ENVIRONMENT Length:43 Volume: Med-High Type (THS, Sport Pattern etc):THS COMMENTS Core: Morph‑Wing™ Core Cover: MicroTrax Pearl Finish: PowerEdge RG: 2.51 (15) Diff: 0.051 (15) PSA: 0.015 (15) ME: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 Axis Tilt: 14° Axis Rotation: 74° PAP: 5 1/8 R 7/8 Up LAYOUT: Pin over Bridge 5 1/4 X 5 1/4 X 2 VLS The HP 5 line is getting it's first pearl offering. The new Transform Pearl teams up the powerful Morph-Wing core with the legendary MicroTrax Pearl cover. The Nano additive gives this cover more footprint than your average Pearl cover and the Morph-Wing creates more progression than your average high performace weight block. This ball gives you more. I tested the Transform Pearl on our House Pattern after a session of senior league. The Transformer made a believer out of me when it comes to the extra progression created by the Morph-Wing core. When the ball shape looked like it was smoothing out to the eye, the Transformer would keep coming through the pins. The Transform keeps this characteristic with a different shape. The microTrax definitely gets the two closer together which I think is an advantange. Some of the pearls are so reactive they cause the ball to get forward much quicker. The Nano additive seems to lengthen the transition slightly but you still see the ball clear the fronts more easily than the solid cover did. The ball looked best on our long house pattern when keeping it in the oil. It would come around for me when I pushed it into the friction, but it really shined in the area that most balls would bog down. Our long pattern creates an area down-lane where most balls wont recover. It is a 12 to 1 so there's plenty of friction up the outside. This usually forces you to either get it right early or hold the breakpoint in closer to the head pin. You can see over/under throwing it right early and as I mentioned a lot of balls bog down in between those two spots. The microtrax begins the ball progressing in the heavy mid-lane oil and the morph wing continues it so you don't have to avoid the soup in the back of the pattern. This ball is going to be very good on all longer oil patterns and it still in play on medium length patterns.

  • Roto Grip Transform Pearl

    Posted by Mike LeViner on Jul 10th 2026

    The Transform Pearl fills a greatly needed spot in the arsenal – strong enough to handle oil while still maintaining a strong backend reaction. In that sense, it is not too dissimilar from the original Transformer, in a way: that ball also does not hook early compared to the heavy oil monsters. The Transform Pearl is the perfect step down from the original Transformer when a cleaner ball is needed. It is best at home on medium oil conditions, though it is not allergic to oil at all. As far as where it fits in the arsenal, I find it fits perfectly between the Transformer and the pearl Gremlin.

  • Transform Pearl Review

    Posted by Adam Chase on Jul 10th 2026

    Layout: 4 1/2 x 4 x 2 (not through Wing) Surface: Power Edge Rev Rate: 470 Tilt: 13* The Transform Pearl brings back the Morph-Wing core from the original Transformer but now paired with the Micro Trax Pearl coverstock which is Nano based. The idea behind this one was to give a stronger and more angular coverstock to handle a little more oil than the original while not needing to utilize the Wing of the core during drilling. What I found on the original Transformer that I have drilled the same as the Transform Pearl; it was too clean for what it was supposed to be used for. The coverstock being much weaker that Micro Trax made the ball give adequate length while still maintaining its smooth shape. While that could be good on some conditions, I preferred my Transformer that was drilled through the wing which gave earlier shape and more continuation for my style. The Transform Pearl for me more closely resembles my second Transformer drilling. I was able to test this on the 50' 2026 PBA Badger Pattern. On the Fresh, the Power Edge made the ball a little too clean to slow down on this long pattern enough. As designed, this will be a better transition ball then a fresh ball in most scenarios. As the pattern broke down around 10 -12 at the break point, this ball shined. The stronger coverstock allowed it to read the midlane well and then friction at the end of the pattern allowed the ball to read adequately. For a heavier oiled pattern, this Transform was able to handle that transition pretty well. The strength of the coverstock made the ball pretty strong off the spot while not being too angular and uncontrollable. I recommend this ball as a step down off a stronger ball then the Transformer such as the 900 Global Viking Conquest or Storm Alpha Crux. The core and cover combination to me puts the ball closer to one of those balls over the Transformer unless it is drilled through the wing. If you like to use stronger asymmetrical pearls in the oil, then this is a good piece to drill. Compared to the Ion Max Pearl, it is slightly cleaner and gives a more angular backend. This Transform Pearl will allow you to open the lane up more easily on medium to heavier oil conditions. https://www.youtube.com/shorts/77Fn_kBgVvE
