I'm a little on the slower side of ball speed and I tend to roll it a little heavy. As a result, I can't throw SUPER strong balls usually. But the UFO is just clean enough that I'm able to use it more effectively. It hooks a ton overall, it's definitely that strong solid asym shape but just clean enough for rev dominant players.

The UFO is the latest technical development in asymmetrical bowling balls that lets the user have a "balance hole" 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 "broken in" 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. I'm 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.

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 that's a great thing, What I did notice is that it did not want to over hook and blended the pattern very well.

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!

The UFO is out of this... I'm 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 doesn't read the front part of the lane quicker. It skids more than most heavy oil hook monster type of balls I've thrown in the past, but still has a smooth and very strong shape. I highly recommend the UFO!

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 doesn't 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 it's 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.

Roto Grip UFO Coverstock: MicroTrax-S20™ Solid Reactive Weight Block: E.T.™ 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.

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.

Layout: 70 x 4 ½ 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.

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 I've 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 asym's don't 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 I've 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!

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.

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 it's 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. 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

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.

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. Stephen Foley. Roto-Grip/Storm Pro Shop Staff.

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 PLAY 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 out 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

Core: E.T.™ Core = Equalizer Technology™ (Asymmetrical) Coverstock: MicroTrax-S20™ Finish: 2000 RG: 2.52 Differential: 0.053 Me: Right-Handed Tweener Speed: 12-13 mph Rev Rate: 315 PAP: 4 7/8 Right 3/8 Up Ball Layout: Pin Up/Right of Ring 55 X 4 3/8 X 35 The New UFO from Roto Grip is an absolute Gem in oil. The Micro-trax S-20 cover gives you superior traction and the powerful new E.T. Core powers this thing start to finish. Design intent with this strong Asymmetric core has been pretty clear. For years guys have been using holes to alter core dynamics and boost mid-lane reaction. The shape of the ET core does that work for you by moving mass to all the right places. The combination of powerful cover and core creates more motion on the slickest patterns. The true key to making a great STRONG ball is keeping the power from detracting from the carry. The UFO does this in spades, it will give you the mid-lane motion no matter what you're bowling on but it doesn't burn up an go through the pins flat. I'm notorious for causing that reaction with stronger balls because of my lower ball speed and no isssues with the UFO. I was really fond of the look I had playing straighter with less hand. Every Pro Shop loves the balls that sell themselves by hook. The rev-challenged bowlers are the life blood of the high performance lines and the UFO is exceptionally well-suited for these bowlers. Strong even read and maximum help creating motion for lower rev styles. This ball will be a staple for anyone looking for "hook-in-a-box""

Length:42 Volume: High Type (THS, Sport Pattern etc):THS Rev Rate: 450 Ball Speed: 17 mph PAP: 5 1/16 x 3/4 up Introducing the UFO, the newest release in the HP4 line. The UFO uses the new E.T. Core = Equalizer Technology wrapped with the new MicroTrax-S20 cover. The layout that I went with was 5 1/2 x 4 x 3 1/2, this layout put the pin under my middle finger. Even with the weaker pin placement, it doesn't stop the UFO! The MicroTrax-S20 cover is super strong and just digs into the oil and goes. It gets going pretty quick and has a strong and continuous arc down lane. If you are looking for a ball for heavier oil conditions, the UFO is the ball to look at!

This ball fit instantly into my bag. It seems to be like a more useable Storm SureLock. I was a fan of the Halo but mine was drilled pin down with a P3 hole. The design intent of the UFO was that the core mimicked a ball that had a weight hole drilled into it. This ball naturally played into my hands. I drilled it pin down, 60x5x70, with no hole. The UFO is clean in the right part of the lane and strong where it needs to be strong. The UFO was exactly what I was needing at the top end of my bag.

The Halo maybe gone, but the UFO is here to stay. Introducing the Roto Grip UFO, the ball is out of this world. Coming in at a 2000 grit MicroTrax-S20 coverstock, with the all new Equalizer Technology "ET" Core. Ever since I put this ball in my bag, scores have not been a problem. I tend to throw the ball a little more firm and quick so with the ET core inside the UFO, it revs up a little quicker but nothing just absolutely crazy. It allows me to move in and swing the lane when necessary or play more direct. It is an absolute hook monster though. It allows me to have versatility in my bag while having a big rolling bowling ball. I've been able to play with some different surface adjustments and it amazed me at how well the ball still rolled with every adjustment. Don't miss out on the opportunity with this ball. It has become a staple in my bag and I know it will be in your bag as well.

If you need hook the UFO has landed and ready to go. This new asymmetric core mixed with the new Micotrax s20 solid creates all the hook so are going to need, This ball rolls real heavy and creates a real nice shape going down lane. The new cover really reads the mids well and when this ball makes a move it goes and goes very continuous and seems not to lose any energy going through the pins. This is going to be a great tourney ball and for those that need a little extra during league play. Grab a UFO before it grabs you

The newest addition to the Roto Grip HP4 line is the UFO. With an RG of 2.52 and differential of .054, the UFO is a very strong, asymmetrical piece that is perfect for conditions with heavier volumes of oil. After drilling one UFO so far, it's been very successful on multiple types of surface and patterns. The one I drilled is mapped out as: 5 x 4 x 75. This puts the pin above my bridge and the mass bias just to the right of my thumb. The UFO provides me a strong, rolly, continuous shape that is perfect for medium-heavier volume patterns. I've had the most success using this earlier in blocks before the lanes transition. It's also a great ball to figure out what pattern we are bowling on and helps determine how much oil is on the lane. From a surface standpoint, I hit it with 3000 and water to take some of the initial surface off and create a bit more length. The response time remains relatively slow, which is expected with such a big engine and strong cover. If you need a ball to help you read the characteristics of a pattern or for medium-to-heavier volumes, the UFO should be added to your tournament / league bags.

Introducing the new "Hook Monster" from Roto Grip. The UFO is Roto Grip's newest big asymmetrical bowling ball that gives players the confidence in a bowling ball that will hook on anything and everything. The UFO has the Equalizer Technology Asymmetrical Core wrapped with the MicroTrax-S20 coverstock. The UFO compared to the original Halo, in my opinion, is slightly cleaner through the front part of the lane and still reads the middle and the backend just as hard as the original Halo. Out one the PBA Tour, this ball has come into play for a lot of players on the heavier volume patterns. This ball also handles surfaces changes very well and you can throw this ball on a wide range of patterns. When you need control and a ball that you know will hook on anything, this is the ball for you. This ball suites all ranges of bowling styles. Whether you're someone that likes to throw it hard, has a lot of rev rate, doesn't have a lot of rev rate, someone that likes to play the lanes straighter, you name it; this ball does it all. Get yours now! You don't want to miss out on this hook monster! Nate Garcia PBA Regional Champion

The new Roto Grip UFO just flat-out hooks!!! The new cover (MicroTrax-S20 Solid) comes with a lot of surface on it (2000 sanded from the factory) and is combined with the new Equalizer Technology asym core (2.52 RG, 0.054 diff, 0.016 int diff) to create a hook monster to end all hook monsters. I've used mine in probably 7-8 different centers, and getting this ball to read the lane and hook has been the least of my worries by a long shot. Even with trying the surface higher than factory (about 4000 sanded) it still never wanted to miss the spot and created an absurd amount of friction throughout the entire lane - almost too much at times for me, given that I have a higher rev rate. What's remarkable about this one is that even on not-super-long patterns it can still get through the pins very well as long as you play more of the oil, rather than the dry, and let the ball do its thing downlane. If you need a ball to pick up when nothing else will... this is the ball for you.

I'm really enjoying the newest HP4 line that Roto Grip has created, the UFO. I've drilled mine pin above the bridge, which is 3 inches pin-pap. I thought that the Gravity Evolve was the strongest ball in my bag, but the UFO has me re thinking that. For being a 'big ball' asymmetric, I still get plenty of continuous motion at the back. It allows me to open up my angles and get left. It'll for sure be the first ball out of my bag on heavy conditions. If you're looking for a ball that HOOKS a ton, and lets you get left without losing energy, then this is the ball for you.
