Halo Pearl
« on: February 27, 2019, 03:02:26 PM »
The Roto Grip Halo Pearl is the perfect compliment to the original Halo bowling ball. This ball utilizes the same proven Centrum Core that was introduced with the Halo but a completely different coverstock. This ball is wrapped in the eTrax-P18 Pearl Reactive coverstock causing it to move at a different part of the lane. This ball offers a footprint in oil while still producing a responsive reaction to friction when lane conditions are medium to medium/heavy oil.

Color: Coal Pearl/Fuchsia Pearl/Sky Blue Pearl
All colors do vary somewhat from the picture shown
Core: Centrum (14#-16#)
Coverstock: eTrax-P18 Pearl Reactive
Finish: 1500-grit Polished
RG: 2.49 (for 15# ball)
Differential: 0.050 (for 15# ball)
Recommended Lane Condition: Medium to Medium/Heavy Oil
Hook Potential: High
Length: Late

See profile for stats.

I drilled my HALO PEARL up 65x5x35 which is my standard layout for large core asymmetric balls. I have left it box since I have only had a chance to throw it on house and a sport pattern that is 45' and it rolls even on that long sport pattern.

This is a great RG pearl like the NO RULES PEARL and CELL PEARL which seemed to never miss the spot downlane. I have been able to throw the HALO PEARL like the other two above on the longer pattern and it holds a lot of energy. It also gives me some good indications when to move out of a zone as it will go forward when it burns too much at the break point. It might still carry the shot, but it is time to go left even more at that point.

I will post when I drill a second one to put some surface on as the NO RULES PEARL and CELL PEARL were excellent balls with surface also.

The Halo Pearl is the latest asymmetric pearl in the HP4 line, a ball that was needed to fill the hole left by the No Rules Pearl, and a worthy piece to complete the trio of reactions.  Like was done with the Idol and Idol Pearl, the Halo Pearl cover formula is quite different from the Halo, but this creates a little more separation and ultimately a ball that is a better compliment.  The Centrum core makes the two reactions feel familiar, but the Halo Pearl is several boards weaker, much cleaner and easier down the lane, and sharper.  For me this means a couple of great reactions that truly compliment each other without the overlap that some balls with the same core and variations of the same cover formula can create.  I have not put the Halo Pearl down since I got it, occasionally Iíll use the Idol Pearl (same cover formula) if the lanes are too dry, but if at all possible, the Halo Pearl has been the ball.  Itís already made me quite a bit of money at tournaments, and Iíve also had a couple honor scores with it, I canít recommend this one enough.

[font=The Halo Pearl, when I first heard of the release of this ball I was really excited. The Halo has been one of my favorites since I drilled it. The Halo Pearl is a great compliment to it. With the cover used on the Idol Pearl was a great choice! I drilled mine Halo Pearl 50 x 5 x 40 very clean when you need more kick in the back this ball provides it! Really nice fit between the Halo and Hyper cell fused!

My name is Doug Cutler and I am a Storm/Roto Grip Staffer.  The first Halo Pearl I drilled is 50 x 5 x 40 and the surface is out of box.  The Roto Grip Halo Pearl sports the eTrax P-18 coverstock and Centrum Core (asymmetrical).  The cover and core combination work very well together.  This ball right now is my go to ball and is a bench mark ball. This ball has given me area left and also right and does not roll out.  You can use this on any THS, and any Sport shot that is medium to heavy oil.  I have had the Halo Pearl for only 3 weeks and the first week shot 833, and next week 749. The 3 week i did not bowl. When this ball starts to go to long, then I go to the original Halo. These two balls are a great 1-2 punch and are a must in your arsenal. #squadRG #halopearl #ownit

My Name is Jay Medina and I am a Storm Staffer. I have my halo pearl drilled  50x5x45 and holy smokes this ball sparks off the back of the pattern. I have named this ball the house shot killer. The ball is really clean through the front of the lane and has hits like a tank. This has really allowed me to open up the lanes especially later in a set without losing any energy through the pins. Compared to the No Rules Pearl for me is was overall about 3 board stronger with a lot more continuation through the pins. I have used this on a THS as well as well as on the Earl Anthony  with a 2000 grit surface. You can find a video here

Layout: 60 x 4 ĺ x 40

The Halo Pearl has massive midlane/backend on medium-heavy to medium-dry oil. This ball loves to turn the corner, and is great for when I have to get left and circle the lane. I drilled it with a layout to enhance the backend reaction, and also left the box finish shine on it, to use when the lanes are broken down a bit and I need to "curve it". It fits that spot perfectly. With the layout and surface that I have on it, it is not ideal for using when I have to go 'down and in'. Other balls such as the first Halo or original Idol are more suited for that, and then the Halo Pearl is the perfect ball to go to when those balls are burning up. The strong backend results in excellent pin carry when this ball matches up properly.

Halo Pearl is a great piece to have in the bag. The E-Trax P-18  cover is one of my favorites. This pearl gets through the heads with ease reads the mids and doesnít quit on the back end. The halo pearl  is perfect for medium oil to heavy oil lane conditions.  If you enjoyed the idol pearl but wished you had something a little less angular at entry point and with more hook this is what you need.

RotoGrip Halo Pearl

Layout- 60x5.5x25

The halo pearl is the pearl asym ball i have always personally wanted. The core is strong enough to dig in the oil but the cover is so clean it always gets through
the front part of the lane. Ive used this ball on 37 feet all the way to 45 feet breakdown in regionals and tournaments. On house its always the right ball.
doesn't respond to quick to the friction all while blending the house shot cliff. the ball is simply a must have in the bag, game 2 ball all the way to the end of blocks sometimes
truly remarkable.

Halo Pearl
« Reply #24 on: May 23, 2019, 01:57:33 PM »

Type (THS, Sport Pattern etc): Various Patterns


Layout: 60 X 3 3/8 x 35
PAP: 5 over 3/4 up

The Halo Pearl is one of the few asymmetrical pearl balls that fits my style. I spin the ball a little more than most, and a lot of asymmetrical pearl balls go way to long for me, and never sees the friction. But, I love this ball. This ball truly does dig through the oil, but is still very clean. I enjoy using this ball during the transition period at PBA events. I'll go to this ball around games 3-4, if not a little earlier. Also, I like to use this ball for THS, and I can play any part of the lane.

If you had the OG Halo, then this ball will go great with it. When the Halo is hooking too early, or not storing enough energy because you're too far left, then that's when the Halo Pearl will come into play. I highly recommend this ball to anyone needs a complimentary ball for an asymmetrical solid.

HALO PEARL - 40 X 4 X 50 - 14lbs.
eTrax-P18 Pearl Reactive - 1500 grit and polished - 6" flare or higher
This is the fourth ball I drilled after my return to bowling and needed a "stronger" piece then the Super Son!Q, needed longer length and same amount of angle to help compensate for my lack of ball speed and changing to 14lbs equiptment. I found the Halo Pearl to be unlike any pearl Roto Grip has had in the past. Even with having the IDOL Pearl with the same cover, the centrum core makes this ball REALLY strong, like He-Man strong. Even with carry down and moving deeper with my feet and changing the angle getting the ball to the breakpoint did not disappoint me or my partner that also tried it. He found that the deeper he played inside, the ball did not quit or give up in the heavier part of the pattern, did not overskid like other pearls in the past with similar layouts. Great BIG PIECE for any league or tournament bowlers.

Roto Grip Halo Pearl

Halo Pearl Ė 5.5 x 5 x 3

Yet another highly anticipated ball from Roto Grip, once the Idol Pearl came out earlier in the bowling season you knew it was only a matter of time before the stronger pearl version of the Halo to come out. Just like with the Idol and Halo, the Halo Pearl has the same cover stock as the Idol Pearl just in the asymmetrical version of it. Halo Pearl is a touch stronger than the Idol Pearl and also a little bit earlier. For everyone who loves either the Idol, Halo and Idol Pearl, the Halo Pearl is another must get from Roto Grip !

Halo Pearl review by Lonnie Pemberton

Type (THS, Sport Pattern etc): THS

Cover: eTrax-P18 Pearl Reactive
Weightblock: Centrum
Finish: 1500 Polish
RG: 2.49
Differential: 0.050

Right-Handed Tweener
Speed: 12-13 mph
Rev Rate: 315
PAP: 4 7/8 Right 3/8 Up

Ball Layout: Pin over bridge 60 X 5 1/4 X 35

The long awaited Pearl version of the Roto Grip Halo is here and it doesn't disappoint. They wrapped the same powerful Centrum Core in the eTrax-P18 Pearl Reactive to unleash the motion on the back-end.

The Halo Pearl takes up the mantle of strong Pearl balls that Roto has always excelled at designing. Imagine a stronger No Rules Pearl. It's a touch earlier but that doesn't reduce it's down-lane hook or back-end capability. This ball hooks and is powerful enough to take on fresh oil. I like this ball in particular on longer oil patterns where you need to see motion in a smaller window of back-end. The angular move will blast the pins without having to cover a ton of boards.

If you're looking for a ball to move in with and wheel the lane, the Halo Pearl shines here too. This ball is incredible continuous from all angles and can keep the pins flying off the deck even when the lane has forced you way in. I recommend slightly lower flaring layouts for lower speed bowlers, or it you are planning to use it more when the fronts have gone.

Length:  Medium

Volume:  Medium

Type (THS, Sport Pattern etc):  THS

The newest addition to RotoGripís HP4line is the Halo Pearl.  The Halo Pearl used the same core as the original Halo, Centrum Core, but the coverstock is the eTrax-18 Pearl reactive.  The eTrax-18 pearl reactive energizes the backend of the Halo Pearl.  The combination of the Centrum Core and the eTrax-18 coverstock produces pin devastation whether you are a Hi Rev player or a Low Rev player like myself!  The Halo Pearl is stronger than the No Rules Pearl especially on the backend.  I was able to throw this monster on a fresh house pattern and a beat up house pattern and the results were the sameÖ  Power from the foul line to the pit! The layout I chose was 5X5X2.5 with no hole and that was based off my PAP which is 5 5/8 over and ĺ up.  The Halo Pearl on the fresh house pattern allowed me to play closer to the oil line and use the friction right to create area.  Usually for me a strong pearl ball will hand cuff me early because of the over under but the Halo Pearl smoothed edge right out.  I could actually miss right and get recovery without worrying about the huge kick left.  As the session continued I could chase left without any problems and the ball made me look great.  The next day on the same pair after a birthday party and cosmic bowling, I had to move two arrows left and make sure I get the Halo Pearl going right to avoid the huge carry down and drier heads.  Usually this leads to a practice session for shooting 10 pins however the Halo Pearl did not lose energy and continued through the pins with force. 

The Halo Pearl is a great addition to the entire line up of RotoGrip bowling balls.  I guarantee this will not be the only Halo Pearl I will drill!

The Halo Pearl is here. It features the Centrum Asymmetrical weight Block and itís wrapped up in ETRAX-p18 pearl. I drilled mine 5 x 3 x 1, my thought process was a to keep energy retention high and turn this thing loose at the end of the pattern. I tested on our house shot which is 42 feet in length with the adult bumpers set to maximum. I am clearly a sprinkler out there ladies and gentleman and I suppose thatís why I tend to favor pearl bowling balls. They suit my plan of attack which is, stay around the ball track, donít miss right and try to hook it a bit. Shooting with the Super SoniQ right before I shot with the Halo Pearl was as close to a perfect ball change as you can get. The Super SoniQ dug in hard and rolled smoothly thru the mid lane, the Halo floats on the front of the lane right before it hits the turbo at the breakpoint. I always show every shot I roll in succession, I feel like it helps people see how the lane is changing and where my bad shots are. The halo was not as forgiving as a solid ball wouldíve been but, letís face the facts, you donít go out and drill a pearl asymm to control the break point, you want to see that ball get crooked down lane. I had a lot fun throwing it.

I would stack this ball right under the Hyper Cell Fused as far as overall strength goes. The hybrid cover on the Fused is clearly stronger and it has a much more predictable shape in the mid lane. The Idol pearl comes to mind as well, that would fit in between the Fused and Halo in total length and the amount of angle that you get.

Why you should buy it? If you liked the No Rules Pearl and are looking for something close to that motion, Iíd say the Halo Pearl is in that wheelhouse. The only negative I found was the color choice. Donít get me wrong, it looks cool but, it seems they got a bit complacent. I feel like Roto Grip is the wild younger brother with a face tattoo who is always causing trouble and people have come to expect bold choices. That is just my opinion, let me know if you agree.

Thank you for checking out my review. Do a good deed today and stop by your favorite RotoGrip Shop, maybe youíll get a HaloÖ.get it?

Roto-Grip Halo Pearl
Layout: 10 x 4 x 45

I used the Halo Pearl to try a new layout. This 10 x 4 x 45 drilling comes out as a pin up for me with a serious mass kick past my VAL. Since the Halo Pearl naturally has quite a bit of length with the ETrax-P18 cover, I wasnít sure exactly what to expect. The end product is one of the cleanest asyms I have thrown without any kind of sharp angle at the breakpoint. I can throw this ball on nearly burnt conditions and it still goes thru the pins. I have also played pretty straight up the lane on sport with success and have hit it with surface to handle a bit more volume. Overall, I am really happy with my experiment.

Although I went with something different on this one, it is still quite obvious this ball has a lot of length. If you are having issues getting the high end balls to go thru the lane and hit, give this one a try.
