Roto Grip created the Halo bowling ball to dominate heavy oil conditions. This ball introduces the Centrum asymmetric super strong core and pairs it with the proven and strong MicroTrax-S18 coverstock. This pairing produces the same type of motion found with the Hyper Cell and No Rules but takes it up a level in strongness!

Color: Coal/Fuchsia/Sky Blue
Core: Centrum (14#-16#)
Coverstock: MicroTrax-S18 Solid
Finish: 2000-grit Pad
RG: 2.49 (for 15# ball)
Differential: 0.050 (for 15# ball)
Recommended Lane Condition: Medium/Heavy to Heavy
Hook Potential: High
Length: Middle

Length: Medium

Volume: Medium

Type (THS, Sport Pattern etc): THS

The RotoGrip Halo is the newest addition to HP4 line of bowling balls.  The combination of the Micro Trax-S18 coverstock and the Asymmetrical Centrum Core provides ultimate Performance on the slickest of lane conditions.  The layout that I used on the Halo is pin over the fingers with the Mass Bias near the thumb with no extra hole.  I have a low rev rate around 300, ball speed around 15 mph, right handed and my axis point is 5 5/8 over and ¾ up.  I threw the Halo on a couple house patterns and the Halo did not disappoint.  Strong throughout the lane with an aggressive move on the backend.  This is not a go long ball and flip but get after it from foul line to pins type of motion.  The Halo being aggressive early and often made me follow the pattern left as it broke down.  Surprisingly, the Halo still motored through the pins but my angles were becoming very drastic.  The Hyper Cell Fused would have been a good go to ball in this situation.  Overall the Halo is a monster among men!

Roto Grip Halo

***Centrum Core***

***2000-grit MicroTrax-S18 Coverstock***

Set up with a strong overall layout for me, 55x4x45

My hope for this release was to take the spot of the strongest solid in my arsenal. I was looking for something that could help me early on heavy oil conditions, something I didn't have at the far, so good with the Halo.

Strong, late-midlane motion. I can use this when most others are looking for something to battle through the oil.

I was considering the CodeX or Sure Lock for this spot in my arsenal but after seeing what the Halo can do, I think I am all set.

***I have also seen the versatility the Halo has--as far as cover changes go. I drilled one for a teammate that liked the ball so much that we drilled a 2nd. Slight adjustment to the layout, 4000 grit cover, and polish---how he goes from one Halo to the next throughout the night***

The most recent release in Roto Grip’s HP4 line is the Halo. The Halo has the MicroTrax-S18 solid cover found on the Idol paired with the Centrum asymmetrical core.

I waited until our MatchMaker to throw the Halo a few times just to get a feel. My home house has high usage, older synthetic lanes that tend to hook early causing some pretty poor carry at times. After seeing my reaction, my sales rep recommended going with a 4 x 6 x 3 layout (pin in the ring finger, mass slightly left of the thumb) to give it a chance. This is a much different layout than my two Idols but I could immediately see some Idol characteristics due to the cover. For me, the difference is on the back part of the lane where the Halo isn’t angular. Instead, with this layout, I see a more rounded, predicable backend motion.

Personally, I need a pattern with some volume and length to throw the Halo. From what I have witnessed thus far, if you struggle to create ball motion due to higher ball speed or lower rev rate, the Halo is a great all around choice.

The Halo has been added to the HP4 line of bowling balls from Roto Grip. Halo uses the same solid MicroTrax S-18 cover as was used on the Idol. The Halo comes from the factory with a 2000 grit abralon finish, which is well suited for medium-heavy to heavy volume lane conditions, depending on the particular bowlers rev rate and ball speed. The Halo has a new weight block called Centrum core. The numbers in 15lb Halo’s are 2.49 Rg, 0.050 Diff with a 0.018 PSA diff.

I used a lower Rg layout on my Halo (3 x 5.5 x 2). I am able to get my intended layout to match how I want my ball to perform on the lanes by using Storm’s VLS layout method. Please visit Storm’s youtube page, as they have done a great job at putting together 3 different videos explaining how each number works to affect ball motion, and when changing those variables, you get different reaction shapes on the lane and motion through the pins. Getting back to the Halo; I chose this layout as I wanted a ball that rolled more controllable off the spot (on higher volume, flatter conditions), without hooking too soon. Basically, when urethane just doesn't have enough read of the oil. Placing the pin at 3” keeps the weight block in a somewhat unstable position (3 ⅜” from PAP being most unstable) as I still wanted the ball to flare because of using on higher volumes of oil. Using the 5.5” PSA placement, makes for a longer transition or slower spin time to the preferred spin axis. This keeps the weight block from getting to the PSA too quickly. The 2” pin buffer placement, is a good inbetween placement, staying away from being too angular (shorter distance from VAL) or too even (longer distance from VAL). With this layout, the Halo has been very good for me in tournament conditions that are as I described above. The Halo doesn’t transition too soon and leave flat seven pins, nor is it too angular off the spot,which allows for a wider pocket when they are tough. Comparing the Halo to my No Rules (same layout but with an X hole), the Halo goes a little longer and has a smoother transition shape.

I like the Halo for its intended purpose. This isn’t a layout I would look to use very often on a house shot, unless it was a shorter length, higher volume pattern. Moving forward with the USBC’s new balance hole rule, it’s a very good idea to make sure to “measure twice, cut once”, as it relates to the layout, because the pro shop operator won’t be able to mask a slightly missed drill, with a balance hole. Surface is the biggest factor in how fast the ball slows down, but layout will dictate the shape the ball makes through the pins for each different bowler. Thank you for taking the time to read my review of the Roto Grip Halo. Own IT!

The Halo is the top of the food chain for RotoGrip. If you need to hook it, this is your new ball. I wanted to write this review a few months ago but, I've had some family situations that put the breaks on a lot of things...anyway. I don't typically like asymm, big cover bowling balls. I track and tilt a bit high and can have some quit happen down lane...I was surprised how much energy was left for the backend, it was crazy how hard of a response this beast makes. I drilled a handful up for some customers with varying styles and all agreed on being impressed with the angle of the Halo. Compared to the NORules Exist, the Halo has a different feel all together, the NRE is strong but more controllable where the Halo digs in and gets it! I can see where both balls could have a place in your bag for some heavier volumes or on the famous wet/dry house shots. Give this rock a go! Great release from Chris and the Grips!!!! #SquadRG

Roto Grip Halo
Coverstock: MicroTrax-S18­™ Solid
Weight Block: Centrum™ Core
Factory Finish:2000-grit Pad
Radius of Gyration: 2.49
Differential: 0.050
PSA Differential: 0.018
Durometer: 73-75 Rex D-scale

Weights: 12-16 lbs.
Product Line: HP4

The HALO is the is the newest ball in the HP4 line. The HALO is A strong ball that out of the box comes with a 2000 grit finish. I found that grit to be perfect for the fresh. As the carry down becomes apparent you can move left and zones and still keep this ball in play. This was a really fun ball to test and see how far I can get left and bang on it. For the league bowler, this will be a great piece for a league ball and for the tournament player this ball is a must. Looking for a strong ball for the fresh, give the HALO a look.
BOWLER STYLE: RH - Stroker Rev Rate: 320 - 350 Ball Speed: 15-16 PAP: 4 7/8 right 5/8 up.

Halo Ball Review
« Reply #22 on: December 08, 2018, 01:34:11 AM »
 Here today to do a ball review on the Roto Grip Halo.In todays bowling world were always looking for more hook and roll in those longer and heavier volume patterns,and i have to say roto grip has just done that.Halo is the most hook i have had in my bag in very long time.I was really impressed when the no rules came out,then after that ball roto grip really didnt have anything that strong in there line intill the halo.Halo is amazing im able to use this ball on pretty much and long patter with those heavier volume.I did leave it out of the box to use and see how the surface would changed does shine up pretty quick lol,but when it does just hit it with a abaron pad and your good to go.For sure a great ball for alot of bowlers with all types of styles out there,also more for bowlers needing that extra help with to much ball speed and not alot hand,also big fan in the colour choice very great looking ball and love the name.

Round Holes No Grips Proshop – Ball Review

Ball:  Rotogrip Halo
Layout: 40x4 1/8x50
Surface:  4000A
Lane Condition:  THS mediumvolume
Lane Surface:  Brunswick Anvilane

Tester:  Andrew
Average:  230
Dexterity:  Right
PAP:  4 9/16>, 3/8U
Rev Rate:  370

This is the first of two Halos I’m going to punch out, along with one Halo Pearl.  This Halo is a ball that I wanted to pickup in the midlane and have a smooth backend reaction.  This is exactly what I got.  I changed the surface from box finish to 500/100/2000/3000/4000 Abralon to tackle our house condition. 

I started a couple boards deeper with my feet and eyes over the Winner Solid.  The ball gave me a nice midlane read with a smooth continuous downlane motion.  I drilled this right before league to throw that night in our scratch league.  I used it every game moving about 10 boards deeper through the night. I was extremely surprised that I was able to stay with the ball all set.  Most nights I need to start balling down around the start of game 3.  But not on this night!  Right off the press I shot 279-279-247 for 805!
