Roto Grip Perfect Gem Bowling Ball

The Perfect GEM features the same GEM core found in the previous versions but now has the AI outer core. The Perfect GEM also features some new tires, E-R1 Solid. This combination produces a ball with a lot more overall shape than the OG but still creates plenty of friction. The Perfect GEM is going to be a great option for me on fresh higher ratio patterns or after balls like the ION Max and Alpha start seeing the front part of the lane too quickly. The Perfect GEM is now available from any Storm VIP Pro Shop! Review Video: https://youtu.be/zgMNjHv4iAw?si=NXB8ISog0guD3UFs

The Perfect Gem is the newest addition to the Roto Grip Line. This new asymmetrical solid features the GEM core (found in the fan favorite original Gem), this time, upgraded with AI technology. The weight block is topped with the ER-1 Solid Reactive Cover Stock. The specification of the Perfect Gem is designed to produce more hook potential, more traction, and more versatility. Ball layout: 70 x 5 3/8 x 40. I tested the ball at my home centers 42ft league pattern. The first thing that came to my mind after the first shot was… “wow, this ball is strong!” Quite possibly the strongest asymmetrical solid I’ve ever thrown. The hook potential in this ball blends so well in the oil, where it picks up easily in the mid lane, resulting in a smooth and controllable backend motion through the pins. While the Alpha Crux and Wicked Gremlin have strong hook potential, the Perfect Gem is just the icing on the cake when it comes to versatility. This ball would work so well when contesting on heavy lane conditions. I also feel as a bonus, like the original Gem, bowlers can also benefit with various surface adjustments for the Perfect Gem to give them more length and control with pleasing results. More strength, more versatility, simply… perfect! If you were a fan of the original Gem or looking to upgrade your arsenal with a big core asymmetrical solid, you’re going to love this beast!

Roto Grip Perfect Gem Cover: E-R1™ Solid Reactive – 2,000 Grit Core: GEM™ + A.I. Core (Asymmetrical) Color: Pink/Rose/Oynx Review: The Gem is back baby! This series has been a home run for that first out of bag bowling ball and not to mention the awesome shelf appeal! If you love those bowling balls that like to move this will not disappoint. The biggest difference in this new version is a slightly more dense core as well as a cleaner look through the front part of the lane. We feel compared to the original Gem this ball is less forward rolling and a little more continuous through the pins. Our style: tweener, 350-375 revs, 16.5mph, layout of choice is 5x4x2 (pin is above bridge). We really like this ball for fresh tournament and house patterns. We often find ourselves beginning with this piece in game 1 and transitioning to something a little smoother down lane in the later part of game 2 and game 3. This ball may not be as versatile as some of the other SPI asym bowling balls but it must not be overlooked for its power on the fresh. It really is a true Gem. This may be more of a niche piece but it is definitely worth checking out at a local matchmaker to see if it fills that gap in your arsenal.

Right Hand - 15.5 mph down lane, 335 +/-, PAP 4.75, 1/2 up, layout is 4.5 x4x2.25. I have bowled on a house shot at Bowlero Edmond, OK and a 44ft 29ml pattern. The Perfect Gem is for the person who wants maximum traction, strong continuation, and plenty of shape when the lanes are fresh and demanding. The only Gem I have rolled prior was the Magic Gem. The Magic Gem was designed to sit between the original Gem and Exotic Gem, offering more length than the original Gem while maintaining substantial midlane traction. The interesting thing about the Perfect Gem is that solid, doesn't necessarily mean earlier or smoother. The new E-R1 cover was designed to get through the front relatively cleanly and then respond strongly to friction. My comparison is that the Magic Gem is skid, strong read, strong continuation and the Perfect Gem is clean, stronger midlane, bigger and more continuous. The Roto Grip Perfect Gem is a powerful heavy-oil weapon. If you're looking for a piece of equipment that can dig through oil, read the midlane and continue through the pins, the Perfect Gem deserves a spot in your bag. The Perfect Gem gives you a stronger overall read while still maintaining enough energy to continue through the pins. For a bowler with decent speed and/or lower rev rate, the Perfect Gem could be particularly interesting because it gives you a way to create traction without necessarily getting the ball to quit downlane. The Perfect Gem is a heavy-oil beast. When the lanes are demanding and you need something that isn't afraid of volume, this is the type of ball you want in your bag. Thanks, Mike Walker

The Perfect Gem might be the most versatile Gem that they have made. Even though the ball doesn’t pick up as early as the original Gem, it is still strong. When the lanes break down I feel like the original Gem didn’t have as much forgiveness when I moved a little left. This ball has a bit more length with a sharper backend motion. It allowed me to play a little more inside and the ball just continued to plow through the pins.

Roto Grip Perfect Gem: Core and cover: GEM + A.I. Core with E-R1 solid cover Factory finish: 2000 grit – Mine is at 500 then 1500 grit with Rough Edge – after testing different cover surfaces to suit my game Layout: 3 ¾ x 5 x 2 ¼ Here we go: The Perfect Gem is the latest high power performance ball from Roto Grip. Following up on the Wicked Gremlin, the Perfect Gem is on the stronger side with the E-R1 cover with the updated GEM cover. E-R1 cover actually “allows the ball to save energy with a booming shape down lane.” Out of the box at 2000 grit, the Perfect Gem was way strong and early in the reaction for me on a medium to heavy volume house pattern with Kegel GLIDE Lane conditioner. I mean STRONG! Like WOW! Holey Moley! So, I started to experiment with surface changes to see what I really had with this ball with the help of the ABC North pro shop haus machine and ball spinner. I tried grits from 3000 to 5000 and just seemed to still be a little early and “booming” in the backend. So, I tried doing a complete reset with 500 then 1500 grits then used Storm Rough Edge on the surface, and I was completely amazed by the reaction and how long I was able to stay with the ball through my whole practice session for more than 1 hour. I decided to use it in league play the past 2 weeks at 2 different centers and I can say with minor target adjustments, I could use the Perfect Gem when I Rock Star was just not getting around the corner enough to get good strike percentage. The Perfect Gem to me with the current cover condition is the best ball to follow up from my Rock Star during league play. I will still be leaning on my Rock Star during practice at league nights, but if I don’t “feel” the Rock Star is the right piece at that point in time, I will have no fear to move right and let the Perfect Gem open up the left side for me. #SquadRG #ABCNorthLanesAndLounge #Coolwick #ViseInserts Upcoming Storm Matchmakers in my area that I will be coordinating and or assisting with: 10/10 – Earl Bowl – Earlington, Pa. 10/11 – Hanover Bowling Centre – Hanover, Pa. 10/25 – Crofton Lanes – Crofton, Md. 10/31 – Shotmaker’s Pro Shop – Perry Hall, Md. 11/7 – Hillview Lanes – Greensburg, Pa.

The Roto Grip Perfect Gem is easily the strongest bowling ball I have ever thrown, and it strikes a ton! Mine is drilled **50×4¾×70**, and this ball has an incredible amount of strength and traction while still being surprisingly versatile. I personally prefer mine with surface, where it becomes an absolute monster for heavy-volume patterns and gives me the confidence to attack conditions where I need maximum traction. What really impressed me, though, is how much the Perfect Gem can be manipulated with surface and for some bowlers, even polish, to create a completely different shape. That versatility makes it much more than just a heavy-oil ball. Whether you need an extremely strong piece for demanding conditions or want to adjust the cover to fit your game, the Perfect Gem gives you plenty of options. If you're looking for serious strength without sacrificing the ability to fine-tune your reaction, this ball is an absolute beast!

The Roto Grip Perfect Gem is an absolute beast when it comes to overall hook and traction! This ball is designed for heavier oil conditions, and you can really feel how strong it is as soon as it hits the lane. The Perfect Gem reads the midlane extremely hard while still giving you plenty of continuation through the pins, making it a great option when you need something that can handle a lot of oil. What I really like about this ball is how much energy it keeps even though it’s so strong. It creates a huge amount of motion downlane and can really open up the lane when you’re struggling to get your other equipment to hook. If you’re looking for a strong, aggressive bowling ball that can handle heavy conditions and give you a ton of confidence when you need hook, the Roto Grip Perfect Gem is definitely a ball worth checking out!

The Roto Grip Perfect Gem is one of those balls that immediately gets my attention once I put it on the lane. With my 50 x 5 x 50 layout, I’m seeing a really strong combination of traction through the front, continuation through the pins, and plenty of shape when it gets to the breakpoint. What I really like about the Perfect Gem is how much confidence it gives me when I need a ball that can handle a little more oil. It picks up in the midlane without feeling lazy downlane, and when it sees friction, it makes a strong and continuous move through the pocket. For my game, I’m able to create a lot of different looks with this ball simply by changing my launch angle and ball speed. It gives me the traction I want in the oil while still maintaining the continuation I need downlane.

I’ve always loved the original Gem because it was so rolly and predictable. I’ve had several 300s with it, so I was really interested to see what the Perfect Gem would do differently. The Perfect Gem is noticeably stronger downlane, with more pop and continuation through the pins. It gives me a different look from the original while still feeling like a ball I can trust when I need to move right (left handed) and open up the lane.

The Perfect Gem gives me exactly what I’m looking for when I need a strong, confident reaction on heavier conditions. It digs into the lane early, gives me a strong and predictable midlane read, and still has plenty of continuation through the pins. Compared to the Original Gem, I see a little more continuation downlane while still getting that strong overall motion the Gem line is known for. Compared to the Magic Gem, the Perfect feels smoother and more predictable for me, especially when I need to control the breakpoint. It fits nicely between the two and gives me a shape that I feel like I can use on a wider variety of heavier conditions. When there’s enough volume and I need something strong, smooth, and dependable, the Perfect Gem is an easy choice.
