Roto Grip RST Hyperdrive Pearl Bowling Ball

The RST HyperDrive Pearl is the latest asymmetric pearl that Roto Grip released. It’s a step up from the Gremlin with a more angular shape. I went in with the thoughts that the ball would be too much ball for me, but I have been pleasantly surprised at how good the ball works for me. I haven’t been this comfortable throwing a big pearl Asym since the original Intense. I can usually use it even on fresh, but it really shines in games 2 and 3 when I need something to get the ball down the lane further. Typically I don’t get a ton of entry angle, but the RST HyperDrive is very angular, to the point that I’ve even managed to throw a few messengers…. And I usually only get 1 of those a year!

Pattern: 42ft House Shot Layout: Dual Angle: 80 x 4 1/4 x 40 2LS: 4.25 x 3 x 6.25 Finish: Box (Power Edge) The Roto Grip RST Hyperdrive Pearl is the latest Asymmetrical Pearl release by SPI. This ball features the RST Block + A.I. Core technology and introduces the U-R1 Pearl reactive cover. This combination ensures optimum energy transfer to drive through the pins with maximum response. Out of the box, I loved how clean it was through the fronts. This ball may go long for some out of the box so don’t be afraid to knock the shine off of it if it’s delaying its response. Overall, this is a great pearl piece to add to the bag if you’re looking for a strong backend motion that doesn’t lose any steam. Trevor Kopas Storm Staff Ambassador Pro Shop Operator #Bigboybowling

Roto Grip Hyperdrive Pearl: Ball details: RST performance core + A.I. core technology with the all new U-R1 reactive cover stock finished with Storm Power Edge factory finish. Layout: 3 x 4 ½ x 4 My Specs: Rev rate 420’s, ball speed 15.3 to 15.8 mph off the hand, axis tilt of 16 degrees and axis rotation of 70 degrees, PAP is 3 15/16th up 3/16th. Tested on Pro-lane surface on a 43ft medium volume house pattern and 37ft sport pattern. The new addition to the Roto Grip HP4 line is the next step up in the pearl coverstock revolution. The all new U-R1 pearl cover is a nano-free cover that is still very responsive, more so than prior pearl covers that were “clean” for me. I went with a different than normal layout for me of a 3 x 4 ½ x 4 to add a different look totally in my bags. This layout put the pin about an inch below my ring finger, the CG about 3 inches left of my thumb and the MB mark down left and actually out of the frame in my pictures. The HDP as I refer to it, has been a breath of fresh air when it comes to the midpoint of matches and tournaments. I will either start with my Roto Grip Rock Star or Gremlin and will migrate to the HDP once I see the back ends are getting a touch more carry down and not seeing the seven pins not being kicked out. The HDP rolls like a Cell Pearl from years and years ago for me and has that special quality of being a ball suited for medium to longer sport patterns and Typical House Patterns, aka; THPs. For me the HDP is that middle ball in my 5 ball league bags right now when it comes to reactive choices. Currently I have in my league bag the Roto Star, Storm Equinox Solid, Roto Star AMPED, HDP, and Gremlin with a long pin, to ride along is a fresh OFF WHITE Mix I picked up at a pro shop over the summer and waited for my RG Jester to be retired.

LANE CONDITION Length: 42' Type:THS - New Bowlero THS Layout: 3 x 5 x 1.25 VLS COMMENTS: Roto Grip RST Hyperdrive Pearl is a great “go-to” pearl ball for medium-length (42') house patterns when you want more length through the front, a strong but controllable mid-lane read, and a clean, angular backend. If you like seeing the ball slide longer and then snap with energy off the spot, this one will be fun. What it does on a 42' house pattern On a 42-foot house pattern (medium oil volume, conventional taper from center lane to outside), the RST Hyperdrive Pearl wants to play from the outside and read the midlane later than a traditional solid. The U-R1 Pearl Reactive Nano Free is special. Expect it to get through the heads with minimal friction, pick up around the breakpoint, and give a fairly defined angular snap to the pocket. Because pearls generally have more skid and a sharper breakpoint, you’ll get a longer skid phase and a quicker, cleaner motion through the pins with the Power Edge Polish similiar to a VEBO with is excellent for carry and for when you need to avoid early hook. My matched speed and revrate gave me super clean length, which made it not as friendly for me. I knocked off the polish with a 1500 pad, added Storm Step 3 Compound and it gave me instant control as of this review. Now this is my 2nd option after my Ion Max/Harsh Reality and Physix Blackout read to early and have difficulty continuing through the pin deck. Mind you I'm playing the track to start and not trying to cover boards while wanting to play where I'm comfortable. Back to the description: Length: Long. The pearl cover helps the ball hold through the heads and delay hooking. Mids: The read is moderate — enough to shape the ball but not mushy. You’ll feel a clear transition from skid to hook. Backend: Defined and angular. The ball doesn’t roll out; it flips with a crisp breakpoint that produces a strong entry angle when you’re in the right lane area. Who this suits: Speed players or higher-rev bowlers who need a ball that will skid longer and then snap — helps keep ball motion from over-reacting in the fronts. Low speed- moderate rev players who like an outside line with a sharp move to the pocket. Bowlers who need a pearl/rescue ball for when their solid balls hook too early or when the lane is starting to transition but still has usable oil. Long, controllable length through the fronts. Clean, angular backend — excellent entry angle and carry. Versatile as a complement to stronger, more solid/continuous balls (Ion Max, Reality). If your bag needs a length-with-flip pearl to complement your heavier rolling balls, the Hyperdrive Pearl is an excellent pick for 42' house patterns. It’s a dependable outside-to-pocket ball that gives confident length and an energetic backend. Rating: 9 - great length and powerful backend; dial in surface for your speed/rev and it becomes a pocket-finding machine. Visit your VIP Proshop today

If you are looking for a strong pearl bowling ball, the Roto Grip RST Hyperdrive Pearl is that ball. This big asymmetrical pearl makes a strong move on the back end. It also has enough teeth to gain traction in the oil and not squirt through the breakpoint. I have thrown this on a house shot as well as a 45’ sport pattern and it has performed will on both. The better looks for me was playing up the lanes as opposed to swinging the lane left to right. Go orders your now or give it a try at a matchmaker event.

The new Roto Grip RST Hyperdrive Pearl features the same Roto Star Tour + A.I. core as the original Hyperdrive, but this version is wrapped in the U-R1 Pearl reactive coverstock and finished with Power Edge. At 15 lbs the RG is 2.25 with a differential of .055 and an intermediate differential of .017. This ball is the perfect compliment to the original Hyperdrive. When the original is losing it’s punch and can’t kick out the corner pins any longer, that’s when it’s time to pull out the Hyperdrive Pearl. The pearl still requires a good amount of oil to be effective, but it is cleaner through the front part of the lane than its predecessor. The pearl version is about 3-4 feet longer before it starts to pick up and features the same strong but smooth backend motion as the original. This ball fits perfectly between the original Hyperdrive and the Roto Grip Gremlin. For me the Gremlin is 2 to 3 boards less overall hook than the Hyperdrive Pearl. Oh and by the way, this ball is an absolute beauty…talk about shelf appeal!!!

I was happy to hear when Roto Grip announced the release of the RST Hyperdrive because the original RST X-1 and RST X-2 have been great balls for me. In fact, I had just asked Steve Kloempken if they could start making the X-2 again and a week later, the RST Hyperdrive Pearl was announced- coincidence? The RST Hyperdrive solid featured the Microtrax (solid version) of what was on the original RSTs. The core has AI added which I feel makes the ball a little earlier in the midlane. Therefore the RST Hyperdrive ended up earlier than X-1 and similar to an Ion Max. I was looking forward to trying the RST Hyperdrive Pearl hoping it would be cleaner and an upgraded version of the X-2. Roto Grip ended up putting a brand new U-R1 (Ultra-Response) pearl coverstock on this one which interestingly is nano free that should help it push down the lane easily. The numbers are same as all the solid. The 15# has high RG of 2.52, but slightly lower that original RSTs which tells me what I feel, the AI core does make it stronger in the midlane. It’s high dif at 0.055 so it has plenty of flare potential and the PSA dif is 0.017. Many compared the Hyperdrive Pearl to the Gremlin released just before. I think the Hyperdrive Pearl is more overall, but similar ball motion. Clean through the front, strong midlane which could get it a little forward, so be careful with the layout if you want it continuous. I drilled mine with pin 4 1/2” from my PAP, PSA 4” from PAP and pin 2” from my VAL (4.5x4x2).

I Drilled the new RST Hyperdrive pearl with a 4.5 inch pin to give me some versatility playing straight and opening up my angles. Thats exaclty what i got with this new ball. The UR1 Pearl paired with the RST Core creates a sharp, angular motion down lane, which is a great step down from the original hyperdrive. This ball fits in the ball 2-3 category for me in a 6 ball arsenal. I can definitely see myself going to this ball when i need to open my angles up or slow my speed down. You won't be disappointed when you pick one of these up!

The Roto Grip RST Hyperdrive Pearl is a great option for me when I want that strong asymmetrical motion but with a cleaner, quicker read through the fronts compared to the solid Hyperdrive. The pearl cover lets it glide with ease through the heads, but the RST core still gives me that heavy roll and strong continuation that defines the line. Compared to the Attention Star, the Hyperdrive Pearl is a little cleaner and more angular. For me, the Hyperdrive Pearl really shines in transition on medium to heavier volume patterns when I still want the strength of an asym but need it to store more energy and drive harder through the pins. Go to your local Storm VIP pro shop today to get yours!

The RST Hyperdrive Pearl builds on what the original solid version started. What makes this ball unique is the combination of a higher RG core and a clean-but-strong cover. As a result, this ball gets to the back of the pattern really easily while also having no trouble handling a fair amount of volume. The lack of NANO additive creates more length and downlane motion than other balls in the product line, but the stronger base formula still lets this ball be first out of the bag on medium friction. Overall, this ball has been really useable for me on medium friction, and I love how quick it is off the spot. This is the quintessential "skid-snap" house shot killer ball. If you like seeing your ball go sideways down lane, you won't want to miss this one! -Chase Valenzuela

So, with the release of the RST Hyperdrive Pearl, you can almost guarantee that Roto Grip delivers another striking success, right? Well, that is precisely what Roto Grip has done! The RST Hyperdrive Pearl is a smooth-rolling, pin-crushing weapon that has a place in any straighter player's arsenal. So, let's take a closer look at what's behind the success of the RST Hyperdrive Pearl, and why it belongs in your bag. Like in the original RST Hyperdrive, the RST (Roto Star Tour) + A.I. core in the RST Hyperdrive Pearl brings a lot of energy and excitement to any straighter player's game. I like how the RST +A.I. Core rolls with a vibrant authority as it makes its way down the lane. And as a straighter player, I loved how the RST +A.I. core builds momentum as the RST Hyperdrive Pearl makes its way through the mid-lane. Unlike other asymmetric cores that tend to be lazy and often "roll out" at the pins, I appreciated how the RST + A.I. core continued to build its energy as it headed down the lane. And with the addition of the A.I. Technology wrapped around the RST block, the RST Hyperdrive Pearl blasts through the pins with a strong and steamrolling continuation that my straighter hand can count on to kick out those pesky corner pins. And when my low rev hand is kicking out corner pins, I know I am in for a great night of scoring! So, the RST + A.I. Core is an excellent fit for straighter players. The U-R1 Pearl Reactive cover on the RST Hyperdrive Pearl took me some time to get dialed in; however, once I found the right surface to fit my game, the RST Hyperdrive Pearl performed exceptionally well. I found that the Power Edge finish for my straighter game caused the RST Hyperdrive Pearl to go a bit too long down the lane before finding its roll phase, resulting in a lot of deflection through the pins. However, I know that as a lower rev player, this is quite a typical response I get from Pearl covers, and surface adjustments can make all the difference. And that is precisely what I found with the U-R1 Pearl reactive coverstock. I hit my RST Hyperdrive Pearl with a 3000-grit Abralon pad, and the RST Hyperdrive Pearl lit up the lanes. With this minor surface adjustment, my RST Hyperdrive Pearl gave me the distinctive skid, hook, and roll I was looking for in the transitioning lane conditions. As the night went on, I loved how the U-R1 Pearl reactive blended the wet and dry conditions, and still had a smooth yet crisp turn off the pattern. So, if you are a straighter, low-rev player like me, don't let the "pearl" coverstock on the RST Hyperdrive Pearl discourage you. The Roto Grip R&D department did a great job creating a pearl that we can tweak to bring us fantastic results. In conclusion, Roto Grip has done a great job in designing the RST Hyperdrive Pearl. Straighter players will find that the RST Hyperdrive Pearl has the power and punch we need to reach the pocket, and the smooth, hard-rolling continuation we need to keep us striking against the competition. So, if you are a straighter player like me, stop into your local Storm VIP Pro Shop today and see how the RST Hyperdrive Pearl will fit into your arsenal.

PAP 5” Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at release 17 Review: The new RST Hyperdrive Pearl is a great looking and great rolling ball! I had this ball for a week or two, but I thought it would be too strong for my league house shot. Man, I was wrong! When I decided to roll the RST Pearl in league, I was very impressed by how easily the ball got down the lane and the back-end move is excellent. I have used this ball in league the last two weeks for all three games and have shot 700 plus both weeks. I do not have a high rev rate, but I am able to migrate left with my feet and target and the ball still gets the corner pins out. The entry angle of this ball for me is perfect and helps my carry substantially from what I was doing the first few weeks of the season. The RST Pearl is stronger than my Typhoon but a bit weaker overall than my Harsh Reality Pearl. The RST Pearl has more back end than the Harsh. I see no reason to change the box surface of this ball. The RST Hyperdrive Pearl has captured a place in my league arsenal for sure. Summary: The RST Hyperdrive Pearl is easy through the front with a great move down lane. The entry angle of this ball enhances pin carry. This ball should be a good fit for many styles of play. Glenn Wendel Storm Pro Shop Staff gwendel@comcast.net www.stormbowling.com

The new release in the HP4 line is the RST Hyperdrive Pearl. I am a huge fan of the original RST Hyperdrive. The motion of the Hyperdrive just fits my roll so well. It has the RG Gem Strength with more motion downlane. So when plant came out with the pearl version I was really looking forward to drilling one. I drilled it with same layout as the solid, 4 3/4 x 4 x 4 pin down. With the new coverstock (U-R1 Pearl Reactive material). Lets just this new cover is very clean through the fronts. I thought the Gremlin's cover was clean, but the RST is longer in my opinion. With this clean cover you get a lot more response off of the friction. At the Storm Matchmakers the RST pearl has been a big hit. With a lot of older lane surfaces out there this days, the RST is a perfect match for the 2nd, 3rd game in league or the later block of tournaments.

The Roto Grip RST Hyperdrive Pearl is a high-end, thoughtfully balanced tool: it marries the power and continuation of a strong core with the finesse of a pearl cover to offer a ball that’s punchy but controllable. It doesn’t try to be the wildest ball in your bag—it tries to be useful in more conditions, and it largely succeeds. I found it to be a great compliment to my Hyperdrive Solid. Both are laid out the same 4x4.25x2 great control but strong backend hook.

RST Hyperdrive Pearl Ball Review The RST Hyperdrive Pearl uses the RST weight block with AI Technology wrapped with the new U-R1 pearl coverstock. The U-R1 is a nano free formulation so it will create a clean motion through the fronts with a powerful continous backend motion. RG-2.52 Diff-.055 Int Diff-.017 Asymmetrical Core Finish-Poweredge I drilled my RST Hyperdrive Pearl 4.5x4.5x4 3/8 using the storm VLS layout system. The RST Hyperdrive Pearlwill be clean through the fronts with a quick response downlane to create a strong continous backend motion. The RST Hyperdrive Pearl will be a great compliment to the original RST Hyperdrive. The original RST Hyperdrive solid will be a great option to start on heavy oil and when it's too strong or too early the Hyperdrive Pearl will be a great option. I also compared the Gremlin to the Hyperdrive Pearl and found the Gremlin to have a more rounded shape downlane.

This is the best pearl ball out. So clean and very responsive to friction. But not snapping off the friction. It rolls of the friction. Very continues though the pins. Not to mention strike percentage is though the roof.. Definitely recommended ?

Dual Angle: 70 x 4 x 25 Vector: 4 x 5 1/2 x 1 1/2 The RST Hyper Drive features the U-R1 Pearl Reactive cover wrapped around the RST Block + AI Core. This ball for me was super clear and angular down lane. I found the Hyper Drive to be a bit cleaner and sharper than my Attention Star. If your looking for a ball to get down the lane but pack a punch this is the ball for you.

The new Hyperdrive Pearl from Roto Grip is the newest addition to the HP4 line and it’s been a complete homerun. I was as huge fan of the original Hyperdrive and when a pearl version was announced, I was excited. The pearl version has been a staple in my bag since I drilled it and I don’t see that changing any time soon. The only difference between the original Hyperdrive and the pearl version is the coverstock. Our wizards in Utah has introduced the U-R1 Pearl Reactive which doesn’t included Nano but still provides an ultra-response time. This makes a huge difference between the original and the pearl and also gives us a nice 1-2 punch as players. In 15 pounds, the RG is 2.52, differential is .055, and PSA is .017. Those numbers tell me this ball wants to fly through the front, but because it has a huge engine, it wants to dig in the mid-lane, but then finish strong in front of the pins for ultimate success. I’ve drilled one so far and really like it. I drilled it a little weaker than the original Hyperdrive for the purpose of trying to use the pearl when I need more shape left to right. It drilled as 5 x 4 x 2. This puts the pin above my bridge and the mass bias just to the right of my thumb. I also scratched the surface with a used 3000 pad just to knock a bit of the shine off. The Hyperdrive Pearl rolls great, looks sweet, and strikes a ton. Go drill one!

The Roto Grip RST Hyperdrive Pearl is a great option for me when I want that strong asymmetrical motion but with a cleaner, quicker read through the fronts compared to the solid Hyperdrive. The pearl cover lets it glide with ease through the heads, but the RST core still gives me that heavy roll and strong continuation that defines the line. Compared to the Attention Star, the Hyperdrive Pearl is a little cleaner and more angular. For me, the Hyperdrive Pearl really shines in transition on medium to heavier volume patterns when I still want the strength of an asym but need it to store more energy and drive harder through the pins.

The RST Hyper Drive Pearl (HDP) is Roto Grips newest HP4 release. The HDP features the same RST core found in the OG but is now wrapped in U-R1 pearl and finished with power edge. I personally wasn’t a huge fame of the RST X-2, it felt too quick and clean. The HDP feels slightly earlier and rounder than the X-2. This offers more control and the ability to use it earlier and longer. The HDP has been my go to two ball in league and I have been able to use it later in tournament blocks. The HDP is available from any Storm VIP Pro Shop! Review Video: https://youtu.be/_ElPAX-Kwf8?si=0Sn-ce1Jy2L4_lKL

Layout: 5 x 4 x 2 Surface: Power Edge Rev Rate: 470 Tilt: 13* The RST Hyperdrive Pearl brings back the RST Block AI core combined with the brand-new U-R1 Pearl Reactive Coverstock. The new coverstock allows this ball to be very clean through the front part of the lane while the strong core lets it read the midlane very well. The length of this ball reminds me of the discontinued RST-X2 but with stronger overall hook. Compared to the RST Hyperdrive Solid, the Pearl is definitely cleaner but gives a lot of the same motion. Is it more responsive, yes. Is it more angular, not so much. The reaction is still a more rounded than angular shape on the lanes. On my 44ft typical house shot, I see a clean motion with a strong midlane and continuous reaction. What is nice about this ball, I find it to be useful to be both as a fresh ball and transition ball. The core and coverstock are strong enough to use it on the fresh as the reaction will not be over/under when there is cleaner backend on the lane. The power edge finish gets the ball down the lane again without being too angular. As the lanes start to transition, I was able to move more into the middle part of the lane while still seeing very good continuation through the pins. I did find it to be a more useful ball in the transition just due to its cleaner cover, but a simple surface change will allow it to be better on the fresh when needed. I did change the surface briefly to 2000 abralon to remove the power edge. The results I found was the ball was still clean, but the surface got the ball to slowed down even faster making it better for more oil. In my testing, I saw more midlane with a slightly more forward reaction down lane. Again, this type of ball reaction will be better for heavier oil and fresher conditions. I recommend this ball for anyone who likes the Hyperdrive Solid but wants a cleaner and more angular reaction. If you didn't have the Solid, the Pearl will be a good ball for the transition in most environments. Removing the power edge polish will allow it to be better on the fresh. This will not be the most angular asymmetrical pearl in the bag but will give a very consistent and continuation reaction great for a lot of different conditions.

Roto Grip RST Hyperdrive Pearl Coverstock: U-R1 Pearl Reactive Finish: Power Edge Core: RST + AI Core RG: 2.52, Diff: 0.055, PSA: 0.017 (15 lb.) VLS Layout: 5 x 4 x 2 1/2 PAP: 5 3/16” right x 5/8” up Rev rate: 400 rpm Average speed: 16.5 mph Location: Prairie Lanes, Sun Prairie WI Pattern: Medium volume THS The Roto Grip RST Hyperdrive Pearl is the latest addition to the HP4 line, this time featuring a new nano-free straight pearl reactive coverstock wrapped around the same proven RST + AI core that was used in the solid version. The intent with this release was to provide a cleaner reaction through the front part of the lane with a strong, responsive, and continuous move at the breakpoint. For me, the Hyperdrive Pearl has proven to be as advertised. I’ve had an opportunity to throw it in league at 3 different houses, and I’ve had no issues with getting this ball to clear the front part of the lane. Compared to other pearl balls that sometimes don’t quite read the middle part of the lane, the Hyperdrive Pearl consistently reads the body of the pattern well and still has plenty of energy to make a defined motion off the back of the lane and into the pins. Even as the lanes transitioned, I was able to move left and stay with the RST Hyperdrive Pearl and it still maintained a clean, strong, and predictable reaction that I very much appreciate. The RST Hyperdrive Pearl is the complement you’d expect to the solid version and is perfect when you want to keep the same line but the original is too early. In comparison to other pearls, I see the Hyperdrive Pearl being the strongest pearl ball in Roto Grip’s current lineup. While it could be the first ball out of your bag on a normal league pattern, I think it’s most at home as the first ball to switch into when the lanes transition and could be used the remainder of the night.

So, with the release of the RST Hyperdrive Pearl, you can almost guarantee that Roto Grip delivers another striking success, right? Well, that is precisely what Roto Grip has done! The RST Hyperdrive Pearl is a smooth-rolling, pin-crushing weapon that has a place in any straighter player's arsenal. So, let's take a closer look at what's behind the success of the RST Hyperdrive Pearl, and why it belongs in your bag. Like in the original RST Hyperdrive, the RST (Roto Star Tour) + A.I. core in the RST Hyperdrive Pearl brings a lot of energy and excitement to any straighter player's game. I like how the RST +A.I. Core rolls with a vibrant authority as it makes its way down the lane. And as a straighter player, I loved how the RST +A.I. core builds momentum as the RST Hyperdrive Pearl makes its way through the mid-lane. Unlike other asymmetric cores that tend to be lazy and often "roll out" at the pins, I appreciated how the RST + A.I. core continued to build its energy as it headed down the lane. And with the addition of the A.I. Technology wrapped around the RST block, the RST Hyperdrive Pearl blasts through the pins with a strong and steamrolling continuation that my straighter hand can count on to kick out those pesky corner pins. And when my low rev hand is kicking out corner pins, I know I am in for a great night of scoring! So, the RST + A.I. Core is an excellent fit for straighter players. The U-R1 Pearl Reactive cover on the RST Hyperdrive Pearl took me some time to get dialed in; however, once I found the right surface to fit my game, the RST Hyperdrive Pearl performed exceptionally well. I found that the Power Edge finish for my straighter game caused the RST Hyperdrive Pearl to go a bit too long down the lane before finding its roll phase, resulting in a lot of deflection through the pins. However, I know that as a lower rev player, this is quite a typical response I get from Pearl covers, and surface adjustments can make all the difference. And that is precisely what I found with the U-R1 Pearl reactive coverstock. I hit my RST Hyperdrive Pearl with a 3000-grit Abralon pad, and the RST Hyperdrive Pearl lit up the lanes. With this minor surface adjustment, my RST Hyperdrive Pearl gave me the distinctive skid, hook, and roll I was looking for in the transitioning lane conditions. As the night went on, I loved how the U-R1 Pearl reactive blended the wet and dry conditions, and still had a smooth yet crisp turn off the pattern. So, if you are a straighter, low-rev player like me, don't let the "pearl" coverstock on the RST Hyperdrive Pearl discourage you. The Roto Grip R&D department did a great job creating a pearl that we can tweak to bring us fantastic results. In conclusion, Roto Grip has done a great job in designing the RST Hyperdrive Pearl. Straighter players will find that the RST Hyperdrive Pearl has the power and punch we need to reach the pocket, and the smooth, hard-rolling continuation we need to keep us striking against the competition.
