Ball NPS Score: Not Available
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

The newest addition to the HP4 line welcomes the Halo which is strong asymmetrical solid bowling ball finished at 2000 grit. If you were a fan of the No Rules and Hyper Cell lines you will be a fan of this ball. The new core (Centrum) inside the Halo was inspired from it's predecessors (No Rules & Hyper Cell). The coverstock features the same surface as was seen in the Idol (MicroTrax - S18).

The layout placed on this ball is 75x4x80 and is pin down. Since majority of my other asymmetrical solids are pin up I wanted to see a different shape on fresh oil conditions; in particular sport conditions. I did test this ball on a house shot and as you can see from the video I tested different parts of the lane with different speed and angles and the ball responded very well to these adjustments.

I was able to move left, slow my ball speed down and have it come back and kick the corners. I was, also, able to get right and throw it harder up the track area. I was very impressed with the different parts of the lanes I could play with this ball.

I could easily see how much earlier this ball rolled for me and that's in particular to the layout that was placed on it. The Halo read a lot sooner than all my other current and prior solid asymmetrical bowling balls which is something I was looking for.

If your looking for a ball to handle heavy oil the Halo will be a great selection to add to your arsenal.

Disclaimer: I did test this ball on a pretty burnt up house shot. They're were quite a few games prior to shooting this video. Personally, it wouldn't be the ideal time to throw this strong/heavy rolling piece of equipment during this lane environment/transition. I believe when you see the Winner video, which was filmed after the Halo, you'll see much better shapes on that given lane environment.

The Halo is exactly what you expect it to be, its the Idol cover with an asym core.  That gives it that predictable and consistent Nano feel for me, and puts it right between the No Rules and No Rules Exist in terms of just about everything.  Its not as continuous as the Idol is, its earlier and a bit slower on the backend, but its a bit more muscle for when the Idol just doesnt start up early enough.  For a full and detailed review:

Roto Grip Halo Review by Casey Murphy

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:  45, 5 , 70

LOVE the Halo.  Idol cover with a brand new Asym core.  The Halo catches more midlane than the Idol and continues through the pins much more.  On a higher volume pattern I had to play almost 5-7 boards deeper with my feet.  If you like the Idol, but wanted more hook in the mids and continuation on the back, then the Halo is the ball to get!
