Roto Grip Transform Pearl – WWRD 7/10/2026
Coverstock: MicroTrax Pearl Reactive Weight Block: Morph-Wing Core RG: 2.51 RG. Diff.: 0.051 Finish: Power Edge Roto Grip’s new Transform Pearl is a Pearl Asymmetrical piece that is good for Medium Volume patterns. PAP is 5 5/16 R 1 3/16 Up. Rev Rate: 400. Speed: 16.5. I drilled this piece with the Pin up between the fingers, CG in the palm, and ½” above the Mass Bias. Just missing the Wing. 5 x 4 x 2. I threw this piece on a Fresh 42’ house pattern. Out of Box ball motion started in the mids with a sharp backend reaction through the pins. I compared this to the Transformer. Similar Layout but I drilled the Mass Bias 1” right of the thumb. I didn’t drill through the wing. It started a few feet earlier with a smother backend reaction. This piece will be good for all types of styles since you can either drill through the wing or away from it.

Transform Pearl
Transform Pearl is a huge spin on the original Transformer! While the core remains the same, the coverstock on the TP is a huge step up in strength/hook potential. The result is an aggressive, somewhat blendy midlane move and a big tip down lane, all in a cover that is really hard to throw through the spot. This shell can handle oil really well, so I can also see this ball being great at blending out wet/dry conditions. I think my favorite spot to use this in is going to be when there's a little early friction but not a ton of free hook down lane. I know this ball will clear the front, but also get off the spot down lane. Even in live-fire so far, I've been able to hook this ball and stay firm and aggressive because i know it's gonna see it and come off of it down lane every time. This strong, dynamic pearl asym adds a whole new dimension to the SPI product line as well. Ion Max Pearl is a little smoother/tumblier, and Gremlin is a mile cleaner and a little sneazy across the cliff. Transform Pearl has quickly made my league bag. You won't be disappointed if you pick one up! -Chase Valenzuela

Transform Pearl
The Transform Pearl is Roto Grip’s newest addition to the HP5 line. It follows the versatility of its successor in the Transformer. The Morph-Wing Core returns, only this time, it’s paired with the MicroTrax Pearl Reactive Cover Stock designed with Nano technology. The results… more traction through the mid lane, more aggressive backend recovery, more versatile ball motion. Like the Transformer, drilling away from or into the Morph Wing Core will determine the proper ball motion bowlers would like to see fit in the Transform Pearl. I decided to drill away from the core, like with my Transformer, at 70 x 5 3/8 x 40. With the strength of the Nano based cover stock, this layout has given me more length, more aggressive but controllable backend. Testing it on my home center’s league pattern (42ft), and comparing it to my Transformer, I was pleased with the results. My Transformer (50 x 4 5/8 x 35) was a little weaker in length, resulting in a more angular ball motion. My Transform Pearl gave me better results, as it was cleaner and more responsive in the back part of the lane. I could move right with my feet navigating the inside part of the lane and the ball can still recover strong enough for great results. In my own opinion, I find the Transform Pearl to be a great upgrade from the RST Hyperdrive Pearl. I had a lot of success on longer patterns with the RST Hyperdrive Pearl and am hoping with its MicroTrax Nano based cover, the Transform Pearl will follow suite. Roto Grip has hit another home run with the Transform Pearl and would be a great fit into your bag when contesting on medium-heavy lane conditions. Drill one up today at your local Storm VIP Pro Shop! You won’t be disappointed!!

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
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 Asymmetric Pearl
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.

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.

Roto Grip Transform Pearl review by Lonnie Pemberton
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.
