Your competition wont be able to identify this object as it flies down the lane. The Roto Grip UFO high performance bowling ball introduces the E.T. Core - Equalizer Technology which has built in "Equalizer Cavities" that take the place of past weight holes to create more midlane movement as well as continuation down the lane. The MicroTrax-S20 Solid Reactive coverstock provides great traction on heavily oiled lanes.

Color: Deep Purple/Baby Blue/Neon Green
All colors do vary somewhat from the picture shown
Core: E.T. = Equalizer Technology (14-16#)
Coverstock: MicroTrax-S20 Solid Reactive
Finish: 2000-grit Pad
RG: 2.52 (for 15# ball)
Differential: 0.054 (for 15# ball)
Recommended Lane Condition: Medium/Heavy to Heavy
Hook Potential: High
Length: Middle

The UFO is out of this world.

WEIGHT BLOCK: E.T. Core = Equalizer Technology
WEIGHT: 15lbs
RG: 2.52
DIFF: 0.054
PSA: 0.016
COVER: MicroTrax-S20
OUT OF BOX: 2000 Grit

Patterns used for review are HP modified.
Pattern A: 40Ft, 24 Mls
Pattern B: 43Ft, 29 Mls

The UFO was able to play both patterns from the inside but favored the longer Pattern B. 

Initially my thoughts were, boy does this guy hook. Heavy continuous arch. Straight out off the box it can be a little intimidating but after a few games as you get oil into the cover it tames down nicely.

Pattern A:
The UFO out of box is a little much for this pattern. The ball picks up really quick that the lighter volume and shorter length leaves little room for error inside of your target.

Pattern B:
This pattern was more appropriate for the UFO. The extra three feet provided the extra hold. So much room for error.  Miss left and the ball is still able to pick up and make a move to the pocket.  Miss right and the ball hits the friction and comes roaring back.

LOW DOWN: The UFO is it of this world. If you struggle getting the ball to read heavy oiled lanes this is the ball for you. The E.T. Core will definitely provide you the extra movement to counter the no extra holes rule that starts at the beginning of the 20/21 bowling season. #SquadRG

The UFO from Roto-Grip is a new kind of alien. Yet another new core and cover combination, this one features the E.T. core with a RG of 2.52, diff .054, and an intermediate diff of .016. It is wrapped with the new MicroTrax-S20 Solid. Another large Asymmetric that I can use a long pin to pap layout of 5x4x2 so it will help get it down lane and have enough energy to turn the corner.
The UFO allows me to open up my angles and move into the heavier part of the oil on a THS. It is strong enough to allow me to miss left and make it back into the pocket. Missing inside with this ball is not an option for me as this ball will still turn up in heavy oil. Do not let the dull cover stock fool you into thinking this ball will not get down lane. Roto-grip does a great job with their dull solids getting plenty of length while maintaining enough energy to drive into the pins.
The UFO for me is going to be best utilized on heavier volumes of oil or longer sport patterns. For those types of patterns, I like to keep things in front of me and keep my angles closed for as long as possible. The larger RG of this ball does just that, it is not as early rolling as the halo, but it is not as long as the Wild Streak either.

Gender: Female
Rev Rate: 315
Ball speed: 16.5 mph
P.A.P: 4-1/2 & 1-1/8

My first impression of the UFO was simple. Wow this thing took over the strongest ball in my bag and I love it. I found it to be super controllable and continuous down lane for a strong asym. I tend to find that my big asymmetric balls roll out very easy but thatís not the case with the UFO. I feel like no matter what rev rate or speed you have this ball will fit everyoneís game, I havenít seen it look bad in anyoneís hand yet. I compared the UFO with the Halo and found that they were similar but the UFO kept driving through the pins where the Halo came in a little weak. My move was about 4/1 left with the UFO. If youíre looking for a strong asymmetric solid that doesnít quit in the back end then youíre looking at it. Would be a great ball to replace that old halo with when the new weight hole rule comes into play.

Take a look for yourself in my video review below!!!Ē

I drilled up my UFO at 55* x 4 1/2" x 30*. I have been throwing this one at box finish of 2000 tru-cut.

The UFO is a bigger core/cover combo for me. I have thrown this one on some modified house patterns and on the PBA50 Billy Hardwick 44 pattern which in 2020 is 44'/28.2 mil condition. On the modified pattern, I had good results with the UFO. It read early enough to keep me from using a 1000 tru-cut GRAVITY EVOLVE. Compared to the EVOLVE, the UFO was slightly weaker up front but had more energy down lane and rolled forward just slightly at the end of the pattern making it a much better option. On the 44 ft/28 mil pattern, the 1000 covered EVOLVE was a better play as it got out of the skid just slightly earlier than the UFO. Once the EVOLVE started to bleed too much energy, then the UFO was in play for much of the remaining games of the block.

Buy this when you want something to pick up earlier than your hybrids with big core motion down lane.

Roto Grip UFO

The new ball from Roto Grip in the HP4 line is the UFO.  This is a strong solid asymmetrical with a lot of hook!  I drilled mine 5 x 5 x 2.  I'm usually not a big fan of big solid asymmetrical balls with my roll.  But the UFO was a huge surprise. The UFO with a little Storm step 2 applied to the cover, this ball was the most overall backend reaction that I have seen in a long time.  UFO is way stronger than the RG Halo. When using this ball on house a couple sport patterns the UFO just keeping hooking. So I just kept chasing it left.  Usually big asymmetrical's will just bleed off to much energy and lose reaction down lane at the breakpoint.  Not the UFO it just kept hooking.  With the new core and cover it created a ball reaction that was different than anything in the line today. This is a great addition to the RG line.

Layout: 65 x 4.75 x 35 My standard pin above the fingers drilling
17 mph ball speed
450 rev rate
42' house shot with high volume
40' modified house shot on 31 year old lanes with High friction and medium volume

For a ball that is probably the strongest ball I've ever thrown, it still has tons of recovery from misses outside. This brand new E.T. core and Micro-Trax coverstock are both very, very strong but don't bleed off energy early. On a Typical house shot with a lower volume of oil, the UFO can be a bit strong. But, show it some Medium-heavy to Heavy oil conditions and this ball is in its element. If you like a heavy rolling ball like the original Halo, but need easier length and tons more recovery, then this is the one. High speed players and low rev players will love this ball. Lower speed and Rev dominant players will need to play in the puddle a little more. Everyone in between can do whatever they want. Its ability to circle the lane and still retain all its energy is amazing. When the 2 handers and Urethane guys push the oil down and create a hang spot, this ball will track right through it. Use your favorite layout and let it do its thing. On a fresh Sport pattern with higher volume i would use a little more surface, like 500 grit, to slow it down on the backend until the lanes open up. #Stormnation #SquadRG

Roto Grip UFO

55 x 4.75 x 20

As someone who utilizes lots of weight holes, I was very interested in this core!  Historically Iíve loved most HP-1 Roto Grip products so I had high hopes going into this one.  I own and operate a pro shop in a bowling center with very high friction 32 year old synthetic lane beds.  Needless to say, the high end duller asymís donít match up the best in our place.  This ball gets through the front as easy as a shiny ball and slows down in the mid-lane very well.  I see more down Lane continuation out of this ball vs Omega Crux.   Based on my surface preparation this could be either my big dull hook monster or my first transition ball when the duller one gets too early and lazy.  So far Iíve been able to stay in this ball longer than expected!  This is a ball I will use on fresh quite often and is definitely intended for heavy and medium volume patterns.  Speed dominant players should like this one!

Layout: 70 x 4 Ĺ x 40

The UFO is the rare medium-heavy oil monster that still has a ton of shape down lane. The UFO got through the front part of the lane easier than I thought it would, and had a strong midlane/backend reaction. I would classify it as more angular than an Idol, but obviously not as skid-flip as the Nuclear Cell. Depending on surface prep, it can cover anything from medium to the heaviest of oil. It is definitely too strong for light oil, but that is where the MVP Pearl or the Hustle line will come into play.

Layout: 70 x 4 x 35

Ball specs:  2000 grit - MicroTrax S20 solid / E.T core

Using on the older HPL with the less blended pattern it was stronger and more angular then the Wild Streak. The UFO came more into play when I got into games 4, 5, and 6 during a recent tournament where the Wild Streak started to weaken due to carry down, the UFO pick up where the Wild Streak left off. The ball was more suited for me on fresh house pattern on SPL with more blend in the pattern. Was able to adjust more on SPL then the HPL, just showing how the surface of the lane panels can create such different looks in the mid lane and roll area in the back end. A good strong step up from the Wild Streak.

Roto Grip UFO

Coverstock: MicroTrax-S20ô Solid Reactive

Weight Block: E.T.ô Core

This ball is strong!

Set up with a strong, earlier layout for me, 45x4x25

This will be my replacement for my Sure Lock as strongest solid (or any cover for that matter) in my arsenal.

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

While strong, it is surprisingly more usable than most other strong solids have been for me. Having a strong assym solid that I can use for multiple games is a new think for me. My style usually keeps me using pearls or mid performance solids.

When my Storm Crux Omega struggles to make the turn on the heavy, this will be my move.

The UFO is the latest solid offering in the HP4 line, replacing the Halo.  Not only does it replace it, but I think it improves on it.  The UFO features the MicroTrax-S20 cover and the new E.T. (Equalizer Technology) core.  The core contains slots at the bottom meant to mimic a weight hole, and the reaction on the lane is dynamic, especially for a nano based solid.  The UFO has plenty of traction, and doesnít seem to burn energy on friction like some other bigger hooking balls can.  The more friction there is, the more the UFO is going to hook, but the more oil there is, the better itís going to perform, because oil is what it was designed for.  The UFO reacts like how I would expect a solid PhysiX to react, it has an aggressively continuous and energetic motion throughout the lane.

The UFO is out of thisÖ Iím not gonna do it. Lol! The UFO is a hook monster. Mine is drilled 90x4x40 because I wanted this ball to be my heavy oil, fast response option in my bag. And I am glad I did! The UFO hooks way more than the previous ball in that spot. What surprises me is the fact that the UFO doesnít read the front part of the lane quicker. It skids more than most heavy oil hook monster type of balls Iíve thrown in the past, but still has a smooth and very strong shape. I highly recommend the UFO!

Type (THS, Sport Pattern etc):THS


As they stated this ball is "Out of this World"! With the new MicroTrax-s=S20 coverstock matched up with the E.T. Core the UFO is a perfect ball for Medium Heavy to Heavy oil conditions. The ability of this ball to grab and make the turn is unbelievable, with no loss of drive through the pocket to send pins flying into the pit. The UFO is a must have in any bowlers arsenal!

Likes:strong backend

High Speed, High Rev

Roto Grip UFO
The UFO from ROTO GRIP reminded me a lot like the Halo. Both balls being a strong asymmetrical solid. I did not get as much testing as I would have liked to do to COVID-19. At this time I hope we are all doing our part and we will be back on the lanes soon enough. Speaking only from a fresh THS this ball wants to hook and thatís a great thing, What I did notice is that it did not want to over hook and blended the pattern very well.

The UFO is the latest technical development in asymmetrical bowling balls that lets the user have a ďbalance holeĒ effect on ball motion without actually drilling an extra hole. The UFO is in the HP4 line from Roto Grip, and uses Micro Trax S-20 cover which creates a lot of traction. The cover has a color combination of deep purple, baby blue and neon green and is finished with a 2000 grit abralon pad. The core of the UFO is called E.T. core (equalizer technology) and creates an Rg of 2.52, a differential of 0.054, and an intermediate diff of 0.016 in 14-16lb balls.

I drilled my UFO with a layout of 4 x 3.5 x 2. I decided on that particular layout to compliment my 4 x 3 x 2 Storm Evolve. Using such a strong layout, I wanted the UFO to be the go to ball on heavy volume, longer oil patterns after the backends get lazy while using the Evolve. The UFO has a lot more traction and angle once the Evolve gets a little lazy from oil carry-down and lane and surface shine. I used the UFO at the box finish for about 20 games, just wiping the oil off between shots and cleaning it with Reacta-Clean at the end of sessions. The UFO started to lose some board coverage, which was fine as it covered plenty of boards out of the box. Using the UFO at this ďbroken inĒ finish was a little too lazy on the 46 foot 2015 Roth/Holman doubles pattern, so I freshened the surface with a green scotchbrite pad, and the ball became a monster, almost giving me too much hook. Suffice to say, the UFO has not disappointed as being that super strong board covering hook monster that a medium rev rate guy like myself looks for at times.

Iím glad I drilled the UFO. I was originally going to pass on it because I had just drilled the Evolve and thought maybe the UFO would be too close to my Physix in reaction. It is different enough to have in the bag when going to a tournament that I know will be on a longer heavier pattern. The UFO is also usable on some over-walled, high volume of oil in the middle of the lane, house conditions, when keeping the ball in the oil. Thank you for reading my review of the Roto Grip UFO.
