Roto Grip Perfect Gem

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.

Where do I begin? The Perfect Gem is a very early ball that provides a good midlane read and continuation in the backend. I have used this ball in fresh conditions, and it cuts through the oil like nothing is there.

Better than the original gem, super strong in midlane and very very forward without sacrificing carry

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 down lane. The Perfect Gem is 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 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 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 — E-R1 Solid Reactive | GEM A.I. Core | RG 2.49 | Diff 0.057 | Box Finish 2000 Grit The Perfect Gem has been a great match for my game with my high rev rate and medium-to-high ball speed. It gives me the strong traction I want in heavier oil, with a strong and predictable midlane read without feeling like it burns up too early. Even with the 2000-grit finish, I still get plenty of energy downlane and a strong continuation through the pins. I really like that I can move inside as the lanes transition without the ball losing its shape. Compared to the Original Gem, I feel like the Perfect Gem gives me a little more length and continuation while still having plenty of overall strength. It doesn't feel overly aggressive off the breakpoint, which makes it easier for me to control with my higher rev rate. When I need a ball that can handle heavier conditions, dig through the oil, and still have enough energy to drive through the pins, the Perfect Gem gives me a lot of confidence and is definitely a ball I want in my bag.

The Perfect GEM by Roto Grip is here! The layout is 5 x 4 x 2 (50 x 5 x 30 using the dual angle layout) This is my first ever GEM from the most popular series. This ball has the new E-R1 coverstock, which makes the ball clear the front part of the lane and provides that EXTREME response downlane. The original GEM was slow and chuggy, so I definitely see more length and backend from this Perfect GEM. Adding the A.I. core with this cover, gives it more punch through the pins. This ball will be great for me on heavier oil conditions and longer oil pattern as well. I will be taking this to a few tournaments this season! If you are looking for that big ball, but want more backend and drive through the pins, the Perfect GEM will be the one for you!

Roto Grip Perfect Gem 5x4x2. Asymmetrical Solid featuring the E-R1 cover with AI core. A lot of bowlers loved the original Gem. Unfortunately my game never really got along with the original because of how early it was and because of my low rotation it never had enough energy once it got to the pins. Perfect Gem has a slightly higher diff allowing it to get through the fronts a little easier and have more pop down lane which allows me to stay more forward with my release without having to worry about the ball bailing. This one is definitely a bit more responsive than the original Gem. I was also pleasantly surprised at how well it continued through the pins for such a strong cover. I can see myself using this on longer and heavier patterns when I need a strong cover but maybe have to cover a little more of the lane. Get yours today at your local Storm VIP Pro Shop #SquadRG

The Roto Grip Perfect Gem features the GEM+AI Core wrapped in the E-R1 Solid Coverstock. I drilled mine 4 x 4 x 1, and after comparing it to my Storm Alpha Crux, the Perfect Gem reads the lane earlier and provides slightly more overall motion. This ball will be ideal for me on the fresh when there’s a decent amount of volume, or when the Ion Max is just a little too strong. I think the Perfect Gem will favor a wide array of patterns, especially those with heavier volumes, giving me a reliable option when I need that earlier, stronger motion. In my bag, I see this ball fitting perfectly between the Ion Max and Viking Conquest in terms of downlane motion, while serving as a slight step up from the Storm Alpha Crux. If you’re looking for a strong, early-reading option to tackle heavier conditions, the Perfect Gem is definitely one to consider!
