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.
