No Rules Pearl
« on: December 09, 2016, 05:41:09 PM »
Throw the rules out the window! Get the Roto Grip No Rules Pearl bowling ball and forget the rules out. Roto Grip has combined the best features of their best cores to create the Chaotic core. This core combines differential stability, consistent axis migration, and defined RG bands to produce a ball that is powerful. Then they kept going. Roto Grip has covered this core with the Amped Pearl coverstock which was designed to create a strong skid/snap reaction. This bowling ball is finished with a 1500-grit factory polish and is best used on medium to medium/heavy oil conditions. Go ahead and break the rules with the Roto Grip No Rules Pearl!

Color: Onyx/Neon Green/Silver
Core: Chaotic (14-16)
Coverstock: Amped Pearl Reactive
Finish: 1500-grit Polished
RG: 2.51 (for 15# ball)
Differential: 0.053 (for 15# ball)
Recommended Lane Condition: Medium to Medium/Heavy oil

Roto Grip No Rules Pearl Review by Brian Watson

  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

Roto Grip Wreck It Review:
Lane Type: Wood

Length: 39ft

Volume: 21ml

Type (THS, Sport Pattern etc): THS


Likes:  Very Strong pearl.  Handles heavy oil and is clean through the fronts.  For a pearl the ball reads the mid lane real well.   
Dislikes: none
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.  Iíve 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.

League average: 205
Not a high rev bowler, more of a smooth stroker

First night out of the box went 247, 222, 233 for 701
Second night shot a 297 game
Absolutely the best ball right now

Likes: ball is very forgiving if you miss outside, it just comes back like a beast

Dislikes: just don't miss inside, it'll take off on you

No Rules Pearl
« Reply #19 on: March 11, 2017, 02:49:54 PM »
Weight:  14 lbs.
Pin Length:  4Ē
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.  Iím happy to say it did not disappoint on either pattern.  It hit very well for me on the both patterns. 

If youíre 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. 
Iíve 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 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 42í sport pattern when the lane had started transitioning and I needed just little more shape on the back.

Right Handed
Ball weight:  15
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 Pearlís 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.  Iíve had quite a few good nights because this ball creates so much room. 

For a strong pearl, it is not sharp, but quite smooth.  Itís 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.  Itís well worth a try for most bowlers.

The Rotocrip No Rules Pearl is one of the more aggressive pearl bowling balls I have ever thrown. The ball is great for heavy-medium oil patterns. It is very clean through the front part of the lanes and then has a strong continuous arc on the backend. I drilled mine with a 55 x 4 1/2 x 35 layout that allowed me to throw the ball on on both house patterns and sport patterns. Unlike most of the other asymmetrical I have thrown this ball does not tumble, meaning its motion is very controllable and it does not roll out or over react. The ball is a perfect compliment to the orginal No Rules for something that is a smoother.

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!

No Rules Pearl

My name is Doug Cutler and I am a Storm/Roto Grip Amateur Staffer. I am Left Handed and throw the ball around 15-17 MPH.  My first No Rules Pearl drilling I put the Pin Under the Ring Finger and the cg kicked out the the left. 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. 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.  I have used this ball on THS and also on sport patterns like Kegel Abby Road, and Kegel Los Angeles,and even on Longer Patterns like Mexico City when the Patterns breaks down and my No Rules Solid hooks to early. This ball is good on Medium to Heavy Oil Patterns.  This is a ball that you will need in your bag and is a very predictable ball and is one of my favorite balls.  Roto Grip has hit another home run with this ball and works very well with the Original No Rules.  So get to your Local Pro Shop and purchase your No Rules Pearl Today. #ownit #norulespearl
