Color: Onyx/Neon Green/Silver Coverstock: Amped™ Pearl Reactive Weight Block: Chaotic™ Core Factory Finish: 1500-grit Polished Flare Potential: High Radius of Gyration (RG): 2.51 Differential (Diff): 0.053 Intermediate Differential (Diff): 0.018 Core Ever wonder what would happen if you took the dominant traits of proven cores and mixed and mashed them all together? Well then look no further. We took differential stability throughout the lane, consistent axis migration and defined RG bands to create our most dynamic and continuous core to date. Can you say dynamic? I knew you could. Cover The idea behind the new Amped™ Pearl coverstock was to formulate a structurally stronger and more pliable pearl material in order create our most skid/snap reaction to date. You are welcome! Condition The No Rules Pearl comes out of the box with a 1500-grit factory polished finish in order to provide a completely different reaction from the No Rules™ solid sanded version. The No Rules Pearl is ideal for those Medium to Medium/ Heavy oil conditions. Like all pearls it can be sanded to battle a little more oil or just to blend out the reaction at the breakpoint.

    Bowler: Keven Williams Hand: Left Speed: 18mph Rev Rate: 450rpm Pattern: Typical House Pattern The Roto Grip No Rules Pearl is one versatile bowling ball! Compared to the original No Rules, the pearl is much cleaner in the front part of the lane. That allows you to throw it on much more conditions. The No Rules Pearl has a great amount of downlane motion which is also very controllable. The Roto Grip No Rules Pearl is a benchmark ball to start any event with!

    Rev Rate: 400 Ball Speed: 17.3 Axis Tilt: 7 Axis Rotation: 45* PAP: 3 3/4 horizontal, 7/8 up Layout: 50 x 5 x 50 This is my current THS-killer. A new stand left, roll right, and strike all night. I believe the No Rules Pearl's cover and early core combination is perfect for the higher volume house pattern we have. It gives me room right and hold in the middle. I've had quite a few good nights because this ball creates so much room. For a strong pearl, it is not sharp, but quite smooth. It's controllable without being considered weak. Currently, this is the first ball out of my bag, especially on a THS. The No Rules Pearl is arguably the best asymmetric pearl on the market. It's well worth a try for most bowlers.

    The No Rules Pearl (NRP) has the same Chaotic Core that was used in the original No Rules, but uses the new Amped pearl coverstock. I drilled my NRP with the pin above my bridge and the mass bias left of my thumb, 5.25 x 4.5 and a pretty big weight hole on my VAL. The Pumped pearl cover is very strong without sacrificing much shape on the back. As I share in my video, this might be one of the strongest pearl covers I have thrown. I am glad I drilled my NRP with a longer pin because that helped give me the shape on the backend I was hoping for with this ball. I would be careful not to drill this ball too strong if you are looking for a sharper shape, unless you are speed dominant or want a smoother shape anyway. I have used the NRP on a number of league patterns as well as many flatter sport patterns. The best look I have had with this ball has been on a 42' sport pattern when the lane had started transitioning and I needed just little more shape on the back.

    Weight: 14 lbs. Pin Length: 4" Drilling: 40X4X40 Pattern Length: 40 ft. Pattern Volume: Medium Pattern Type: House Right Handed The No Rules Pearl has the new Micro DNA Pearl Reactive coverstock which gives 5% more traction than the proven Micro Bite cover stock from the Defiant line. This new coverstock is wrapped around the new Chaotic Core and comes out of the box at 1500 grit polished, but can be sanded. The flare potential on this ball is high. I have used the No Rules Pearl on house patterns in 3 different houses. For our 40 ft. house pattern, I was able to stay in the playable area once the No Rules starting to be too much, as the lanes transitioned. This ball gets through the heads so clean and stores a ton of energy on the back end. It gives me a very strong angular motion, which helps with the corner pins. I also used the No Rules Pearl on a 39 ft pattern. I'm happy to say it did not disappoint on either pattern. It hit very well for me on the both patterns. If you're looking for a strong, pearl ball to go to when your No Rules starts burning up, the No Rules Pearl is a must in your arsenal. I've also experimented with surface changes, bringing it to 1000, with light polish. This tamed down the snappiness, which allowed me to start with it on the 39 ft. pattern. It gave me more of a roll arch motion. I highly recommend the No Rules Pearl, as either a starting ball on house pattern, or a go to ball from your No Rules.

    The Roto Grip No Rules Pearl is Roto Grips newest HP4 Release. This ball is the Pearl version of the No Rules. Its covered with the Amped cover stock and is finished at 1500 grit polished. The ball hosts the Chaotic Core which is also found in the No Rules. I drilled my No rules pearl pin down under the bridge with the mass bias in the thumb. A stacked layout. I wanted to try something new for me especially with pin downs. I hoped to get the ball do be smoother down lane but strong like the No rules should be. By drilling it with this layout the ball reads the mid lane really well and has a nice arc off the break point. I've used the No Rules pearl on house shots and on medium long sport shots. This ball has become a favorite of mine because of its shape and total reaction. A must have for the advanced bowler. I recommend this ball for anyone looking for a strong backend reaction on fresh lanes with crisp back ends. This ball would also be great for bowlers with less hand who could use the extra help. I believe there is many ways to layout this ball to get it to do different things.

    The RG No Rules Pearl is the pearl version of the No Rules Solid. I drilled mine 5 x 4 x 2 no hole. For me the Utah Pearl covers seem to be a lot stronger reaction than the solids and hybirds at times. With the NR Pearl no exception. With the very strong diff. core of 0.053 it rolls very strong in midlane but with pearl cover it has more continuation down lane. I added a little surface to the cover to blend out the overall reaction. I can use the ball on heaver oiled house shots and most of the medium to longer sport patterns. The NR Pearl has been a very popular choice among lefties and lower to medium rev rate players. A very good addition to the RG line! PAP - 5/8 up 1 1/4 Speed -16-17 Rev Rate- 400 Tilt -15

    The No Rules Pearl is the follow up pearlized version of the No Rules in the HP4 line of balls from Roto Grip. The pearl cover called Amped has an attractive onyx/neon green/silver color combination and is finished to a 1500 grit polish. This cover change from the micro DNA on the solid, creates a reaction more suited for medium oiled lane conditions. The No Rules pearl uses the same Chaotic core found in the solid version, which has an RG of 2.51, a differential of .053, and an intermediate differential of 0.018, in 15lb bowling balls. I drilled the No Rules Pearl 4 x 5 ¾ x 2 ¾. I choose this layout mainly to maximize mistake room and generate a large amount of flare when bowling on high scoring league conditions. The first time using the ball subbing on a 39 foot high scoring house pattern, I shot games of 300, 245, 300 for 845. I would say that I succeeded in picking the proper layout for the conditions and ball. The No Rules pearl gives me good length, with a controllable change of direction at the breakpoint. Comparing the No Rules pearl to my Dare Devil (both balls using the new Amped cover) with a layout of 4 ¾ x 5 ¼ x 2 ½ on the Dare Devil; the No Rules has a slightly later read of the midlane, and has a more defined change of direction, and roll toward the pocket than the Dare Devil. As I remember some of the shapes that some older equipment made throughout the years, the No Rules pearl reminds me most of my Gravity Shift, in that both balls seemed to be easy to get through the heads and to the breakpoint, but didn't over react once hitting the dry part of the lane, as sometimes pearl balls do for me. I've used the No Rules Pearl on a few different house patterns so far, all with good success. I seem to be able to chase the pattern in on the lane, as the oil breaks down, or go a little straighter and bump the wall on tighter typical league conditions. I really like the combination of cover and core with the No Rules pearl. Also, Roto Grip is really on to something with this pearl Amped cover, as both the No Rules pearl and the Dare Devil rolls great for me. Thank you for taking the time to read my review of the No Rules pearl by Roto Grip.

    No Rules Pearl is the newest ball in Roto Grip's HP4 line. This is the most aggressive pearl ball I've ever thrown. It hooks continuously throughout the lane, it has a very strong arc, it is a GREAT ball to use from deeper angles on heavier volume patterns once the transition has forced you inside. It rolls heavy enough and has enough traction that you can project it or fade it through the soup in the middle knowing it's going to pull up and make a STRONG move through the pins. It's just a strong ball in all phases of motion, but the surface finish gets it down the lane without bleeding energy. It's quick off friction, but it doesn't burn or stand up. It also doesn't need the shine taken off to compete on sport patterns, in fact it's better with the factory polish on it. This is one of my personal favorites at the moment, it's very easy to throw with confidence. https://www.youtube.com/watch?v=wXDe0cVEGfo

    The RotoGrip NO Rules Pearl is the newest addition the HP4 line of bowling balls. The NO Rules Pearl features the Chaotic Core which is also in the No Rules. The difference is the AMPED Pearl coverstock that provides skid through the front part of the lane and a devastating hooking motion on the backend. The layout I used on the NO Rules Pearl was pin in the ring finger with no extra hole. I believe the coordinates for the dual angle are 50 X 5 X 50 and that is off my PAP which is 5 5/8 over and 5/8 up. I was able to compare a RotoGrip Skid and The NO Rules Pearl on a couple of different conditions to see what the main differences were. I used the same layout with a RotoGrip Skid and it provided decent length with a controllable backend motion. What I noticed immediately was that the NO Rules Pearl was easily 5 boards more hook and slightly earlier. However, the biggest difference was in the backend motion... The NO Rules Pearl was more violent and powerful than the Skid. This powerful motion helps when moving left and going around the pattern as it breaks down or carries down especially on a house pattern. However, this powerful motion could cause severe wet dry because you have to play so much area. I believe with a surface adjustment the NO Rules Pearl could become more versatile and readable. The NO Rules Pearl will make its way into my bowling bag for the occasions when more is better! The NO Rules Pearl is the go long hooks hard and hits like truck bowling ball!

    The new Roto Grip No Rules Pearl is a perfect compliment to the original No Rules. By keeping the same engine in both balls, but changing the cover to a pearl, the No Rules Pearl is a perfect addition to the Roto Grip line. As expected, the pearl cover creates more push through the front part of the lane and speeds up the response time when it sees friction. I've drilled two No Rules pearls so far. The first one is mapped out as: 5 x 4 ½ x 75. This puts the pin above my bridge and the mass bias just to the right of my thumb. I've been able to use this one on house conditions and sport patterns when the pattern blends out. The layout and cover both create more length and a quicker response time than the first No Rules. The second one is mapped out as 5 ½ x 4 x 35. I also brought the surface down to 1000 with this one. This one reads the lane much earlier because of the stronger mass bias as well as the surface. I've been able to use this one more on sport patterns because of how much earlier it picks up. The No Rules Pearl has become a favorite in my bag and it goes everywhere. Go drill one of the best balls on the market today! #OwnIt

    Oh Baby!!! Another beast produced by Roto Grip! If you want a ball that is strong and continuous this is the ball to get your hands on. This asymmetrical peralized version of the original No Rules gets super clean through the front yet picks up in the back end and does not stop hooking. I have been using this on sport patterns around games 3 and on and this ball has been perfect. I did remove the polish to blend out the patterns a little bit better. Definitely one of my favorite balls in my arsenal right now.

    No Rules Pearl The new HP4 release is the No Rules Pearl. The No Rules Pearl is drilled to compliment my No Rules solid. It is a lot cleaner through the fronts and is strong off of the dry with a strong continuous movement through the pins. The No Rules Pearl is so strong that I could keep moving left and had no problem kicking the corner pins to the middle. On a house shot I kept getting rewarded for most all questionable shots. The longer I kept the No Rules Pearl in the oil, the stronger the down lane motion was, if I didn't send it out to the dry it would hold pocket and put ten in the pit. For a big ball Pearl this No Rules Pearl doesn't over react but it really reads the mid lane very well. With all Roto Grip and Storm equipment, they take to the smallest surface adjustments, then it's like having a different ball with each adjustment. Another great rolling and hitting ball with great looks. Great ball for all types of bowlers.

    Layout: 50 x 4 x 50 Finish: 1500 grit polish Test patterns: 41ft THS and 37ft sport pattern Reaction: Not my typical Asym ball reaction. I usually struggle to match up with Pearls with pin up or pin thru my ring finger. But in this case I listen to my good friends at Bowlers Supply and decided to try a mid length pin and conservative back angle. For me this ball went longer and less angular on both patterns then my Dare Devil with pin up. When I see my Dare Devil starting to hook a little earlier off of the pattern, my next move is to the NRP without any movement. Its longer and stronger but less of an angle into the pocket, which is something I have been working on thanks to Brad Angelo's helpful tips last fall. This ball reminds me a lot of the Totally Defiant and the Mutant Cell Pearl, strong but not super angular and not super aggressive. Great THS ball for people bowling on HPL or older SPL. Sport pattern length best used on was 37ft to 44ft patterns. First ball out of the bag when I bowl anywhere outside of my home center...

    The new HP4 release is the No Rules Pearl. This ball is the perfect compliment to the original No Rules, it's longer down lane and has twice as much angle. If you're bowling and the track starts to burn on you, grab the pearl, move left and let her rip. We drilled up a few in my shop for our Roto-Heads and the feed back has been great. It plays well on fresh as long as you get the ball some friction...I'm slightly speed dominant and have low axis tilt, my asymmetric equipment tends to burn up a bit quick, so I put a 70x5x40 layout on my NP Pearl. I did not have a nice look on my first game during league, so I bagged the pearl until the track opened up a bit. Once I had more miss room right, this new rock shined! I tossed some horrible shots, this ball came back screaming and scattered pins with ease. I know we are all familiar with the "this ain't coming back..." shot, trust me, it gets back! If you have a spot in your bag for a new pearl asymm. or a customer that loves to rev it up and get it right....this is the ball to drill! Thanks for reading and good luck on the lanes. #rotogrip #ownit

    Orientation: Right Handed Rev Rate: 375 RPM Speed: 16-17 MPH PAP: 4 5/8 straight across Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS Layout: 40, 5 7/8, 40 The No Rules Pearl is exactly what you would expect a pearl version of the No Rules to be. It gets down the lane a lot easier than the No Rules and backend a good deal more. As with the No Rules, you see a lot of backend continuation for an Asymmetrical. The No Rules Pearl creates a lot of midlane roll because of the core, and then you see a strong continuous motion on the back. It's the perfect ball for those looking for a slightly cleaner version of the No Rules.

    The No Rules Pearl is amazing. I drilled mine 4x4x2 and my PAP is 4 5/8 x 11/16. I play 35 to 5 and what I love about the No Rules Pearl is that when I am playing this line the ball is not overly aggressive it has a smooth controllable, predictable and easy to adjust break point. If I miss inside the ball reads well and does not overreact, she sits inside and still commands the pocket as if I played way outside. The one thing I look for in a bowling ball for me is how well does it read the middle part of the lane. This ball reads the middle part of the lane amazingly and if she finds a dry spot she continues through until she is supposed to hook. I drilled this up and out of the box I shot a 300. Over the last 8 days of bowling and 2 tournaments I have average 244.72. This ball is a must for all bowlers and you will not be disappointed. I wasn't.

    Roto Grip No Rules Pearl Layout: pin below the bridge with the mass bias an inch and half to the right of thumb,oob Condition: 40 ft house on hpl I drilled this ball wanting to compliment my no rules of course. This ball is very clean through the heads and is strong off the dry and explodes through the pins. I was able to move into the oil and had no problem getting to the pocket and still kicked out the corner pins with ease. The layout I put on this ball allows me to get a strong roll in the oil without an over reaction and strong hitting power. The shelf appeal on this ball is beautiful. A nice green, black and silver scheme that is just eye catching. This is another hit from Roto Grip, it releases on January 10th. Get out and see your local pro shop operator and pick one up, you won't be disappointed. If your in the Evansville,IN area go out see Nick Austin at the The Bowling Place, he will take care of all your bowling needs.
