Transform Pearl Review
Ball Specs: Roto Grip Transform Pearl Micro Trax Pearl Reactive Asymmetric Morph Wing Core Finish: Power Edge Layout: 4 x 4 with 2” Pin Buffer Bowler Specs: Right Hand. PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: The new Transform Pearl is the second in the series using the Morph Wing core technology. This core allows the ball driller to modify ball motion to a better degree by removing a specific part of the core or leaving it more intact. I decided to drill mine missing the top of the wing to enhance down lane reaction. The Transform Pearl is a great looking and great rolling ball! This ball is strong but very usable on various lane conditions. The Transform pearl easily gets down the lane without going past my break point and the back-end move is excellent. This ball hits hard and carries like a champ. Light hits throw pins around nicely which helps carry percent. Transform Pearl is stronger than my Viking but a bit weaker overall than my Harsh Reality Pearl. The Transform Pearl seems to roll later than my Harsh reality Pearl. The Transform Pearl has more back end than the Harsh. I see no reason to change the box surface of this ball. The Transform Pearl will be a great addition for the fall season. Summary: The Transform Pearl is easy through the front with a great move down lane. The entry angle of this ball enhances pin carry. I love the color of this ball and it looks great while it rolls.

Hook Monster!
The Roto Grip Transform Pearl is built to create effortless length through the front of the lane while delivering a powerful, angular move off the backend. Wrapped in the eTrax PLUS Pearl coverstock and powered by the high-performance Rondure MaxD core, this ball stores energy exceptionally well before making a strong, continuous turn toward the pocket. It's an ideal choice for medium to medium-heavy oil conditions when you need more downlane motion without sacrificing continuation through the pins. The Transform Pearl blends responsiveness and predictability, giving bowlers the confidence to open up the lane while still maintaining excellent control. Whether you're looking to complement a stronger solid or simply want a pearl that can create impressive entry angle and carry, the Transform Pearl offers the versatility and hitting power needed to excel in league play and tournament competition alike.

Roto Grip Transform Pearl Review by Lonnie Pemberton
TESTING ENVIRONMENT Length:43 Volume: Med-High Type (THS, Sport Pattern etc):THS COMMENTS 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.

Transform Pearl
The Transformer Pearl is a great step down from stronger asymmetrical pieces while still delivering plenty of continuation through the pins. It glides easily through the front of the lane, stores energy exceptionally well, and makes a strong, continuous move off the breakpoint without being overly angular. When I need to create more angle on transition or open up the lane, the Transformer Pearl gives me the confidence to move left and trust that it will recover consistently and finish through the pocket.

Transform Pearl
The layout is 4 3/4 x 4 1/2 x 4 (55 x 4 3/4 x 65 using the dual angle layout). This is the pearl version of the Transformer. It provides a great midlane motion, while providing amazing motion in the backend! I chose this pin down layout to keep my angles closer to me, but it allows me more miss room when I miss inside target and if I miss right from my target. Speed can definitely play a factor on ball motion. I enjoyed throwing this ball and will be taking it with me to leagues and tournaments! If you are looking for a ball motion like this, I highly recommend this Transform Pearl!

Transform Pearl
The Roto Grip Transform Pearl has quickly become one of my favorite options when I need a stronger pearl reaction. Mine is drilled 45×5×30 with a PAP of 4 1/8" right and 7/8" up, and the ball does an incredible job of getting through the front part of the lane while maintaining the strong, continuous motion you'd expect from an asymmetrical weight block. It has easily become the strongest pearl-covered ball I've thrown in the Storm family, making it an outstanding choice on house conditions or whenever stronger solids begin to read too early. The Transform Pearl stores plenty of energy, creates a powerful move off the pattern, and never sacrifices continuation through the pins. If you're looking for a clean asymmetrical pearl that delivers both length and a strong backend without giving up control, the Transform Pearl is an excellent addition to any arsenal.

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
