    Roto Grip Rubicon UC2 Ball Review by PJ Haggerty The Roto Grip Rubicon UC2 is the newest addition to the HP3 line and I LOVE it. I'm a big fan of the original Rubicon and when a pearl version was released, I was pumped to be able to throw it. The UC2 provides numbers of 2.49 and .052, respectively. Along with a pearl coverstock, the UC2 is a clean, quick-responsive, asymmetrical ball that is a perfect addition to the current lineup of equipment. I've only needed to drill one UC2 and I think it's a home run. When the original Rubicon starts to bog down and I need to open my angles with a quick response time, the UC2 is a perfect ball to go to. Also, I've had the most success with the UC2 on medium-longer patterns. The RG suggests it should be very good on those types of patterns with higher amounts of volume too. Lastly, when patterns blend and break down, the UC2 is a perfect ball to go right-to-left with a quick response time. If you need a ball that does the right thing when you need it, especially if you need to cover some boards, the Rubicon UC2 could be a perfect fit!

    After throwing this ball instantly knew that this was going to be a must in the bag. For being an asymmetrical bowling ball this ball gets straight through the fronts and has pop off the spot. The ball reacts more like a symmetrical then an asymmetrical bowling ball. The UC2 is a house shot monster. Great for fresh or if you need to move in and open your angles it will be very versatile to play on the burn. Visit your local pro shop and grab one of the best balls out on the market today!

    Rubicon UC2 Layout - 55 x 5 x 30 Holy smokes this ball in impressive! Super clean thru the front and all the backend you'd ever want. I was not one that matched up well with the Idol Pearl and feel I've been missing that ball in my bag. Boy is this one a home run! Great looking ball, super versatile cover, don't be afraid to knock the shine off if you want to smooth it out a bit. I've drilled one pin up and one pin down and both are very usable! I would say its cleaner and longer than a Zen and Nuclear Cell. If you are looking for a phenomenal all purpose ball, look no further! She good!

    The Rubicon UC2 is one of the most angular pieces of equipment ever released. It will glide effortlessly throughout the front portion of the lane and make a controllable but large-angle towards the pocket in the back. This ball is perfect for league/tournament patterns that get worn out quickly. With that said, this ball has its uses for fresh patterns as well due to its great ability to generate angle. It will make keeping yourself in play easier for longer on any pattern. The UC2 will find success for players of all forms, styles, and speeds. Personally, I laid out my Rubicon UC2 pin down to tame the overall angle ever so slightly. I have found success on fresh and burn with this bowling ball for the same reason, it is very clean through the front but saves a ton of energy for the pins on the back. When lanes begin to dry out, this ball is my go-to and it allows me to strike from all angles in the pocket(and sometimes out of it as well). This piece has a place in every league/tournament arsenal! -Matt Hibbard 900 Global Regional Staff

Wow! What a clean ball through the fronts then a big back end motion. The backend recovery is really impressive. The UC2 will be a house shot wrecker and one of your first options if you need to move left and throw it to the right. The UC2 is already becoming a favorite on the PBA tour. A great color scheme just adds to its appeal. Visit your local Storm VIP Pro Shop! #Stormnation #SquadRG

    UC2 will be 1 if those balls that stays around for a long time. It's that good and that useable. The ease it gets threw the front with along with it's strong recovery will not only make it into everyone's league bag but it will also be a must for tournaments. The ball is not only useable but it's fantastic from many different angles. You can't ask for much more!

    The first thing I thought out of my hand was WOW. This ball immediately showed me energy through the pins without feeling like I had to search for it. The lower RG allows the ball to easily rev off the hand and the Medium Diff doesn't make it track up too early at all. I also love that Roto grip went with a lower mid diff that seems to allow the ball to not quit all the way through the back of the pin deck. I have thrown UC2 now 2 weeks and both times allowed me to play multiple angles with it through the front and was strong enough on a fresh house shot I didn't feel like I needed more to start with. I drilled my UC2 at 50*x4.5x75* putting the pin just below my ring finger and kicking the mass bias out towards my PAP. (PAP= 5 ⅝+¾) When choosing this layout I was looking for a smooth continuation with very little energy loss at the breakpoint This ball gave me exactly that. Altho I will say the UC2 has a backend motion that will still drop some jaws I feel like I can be confident in where it is going and how it will get through the deck. The first night I threw the UC2 I struggled game one with a different ball and switched game 2. The next 2 games I went 244, 268. Within those 2 games I had 3 shots that went through the deck so hard that the 3pin got sucked straight back into the 9 pin as the ball drove through the 8. I know this is not how it is supposed to work but the reason for telling you this is the ball has insane energy and seems to carry even the off hits in ways I have seldom seen before. I think the Rubicon UC2 will be an amazing ball on all kinds of oil patterns and is looking to be that ball that will from now on go EVERYWHERE with me. I cant think of a bowler this ball wouldn't fit somewhere in the bag for.

    The Rubicon UC2 features the etrax pearl cover and mild asymmetric Rondure core. The eTrax formula has been used in several iterations in the HP3 and HP4 lines over the last few years, and this version of the formula is the pearl version of the Idol Synergy cover. The Rondure core comes in at a 2.49 RG, .052 differential, and .011 split or intermediate differential in 15 pounds, the idea again being to mimic a stronger symmetric ball with a weight hole. The original Rubicon was already pretty quick on friction despite being a solid, with the cleaner eTrax base formula on it, it definitely punched a lot, and the UC2 takes that up to 9000. It's very quick on friction and very easily controlled and manipulated with physical adjustments, I can play virtually anywhere I want to with this ball as you'll see here in a few seconds. It's becoming a favorite of both Angel and mine because it's very easy down the lane and turns quickly on friction, while being a lot more consistent than you might expect it to be. It gets easy length for Angel and more punch than she gets out of literally anything else in her bag, and for me it's something I can float out of and still get a sharp and visually comfortable move on the backend. In addition, if I need to get deep, there are no angles it won't recover from, at least if you're on the right conditions for it. The Rubicon UC2 is a ton of fun, it's moved its way into both of our main league bags, and paired with the Rubicon, they're a pretty devastating combo. I give the Rubicon UC2 a 7 for hook, 7 for length, and a 9 for backend strength.

    Cover: eTrax Reactive Pearl RG: 2.49 Diff:0.052 PSA: 0.011 This ball is awesome!! I liked the Rubicon Solid a lot when it was released. However, I have been looking for a pearl ball with this ball motion since I switched companies. This ball was a pleasant surprise for me. The layout is 60 X 3 ¼ x 45. The UC2 is cleaner down lane and picks up and drives through the pocket. I was surprised how well it blended out the house shot I bowl on when the lanes broke down. When others were leaving corner pins, I was carrying the pocket and the ball was still getting through the pins. I can create shape with the UC2 and trust it will turn the corner. I did hit it with 3000 which made it a bit smoother and doesn't' jump of the friction. Lately this has been the first ball out of the bag!! I highly recommend the UC2 if you are looking for that stronger Asymmetrical ball that will fit pretty much all styles of play you won't be disappointed.

    The Roto Grip Rubicon UC2 brings a shiny pearl version of the original Rubicon to the line, and it's everything you expect and then some! An updated version of eTrax Pearl (Idol Pearl, Halo Pearl) with the same mildly-asymmetric Rondure core from the original Rubicon. The overall shape feels very reminiscent of the original Rubicon just getting further down the lane and turning harder once it sees friction - which also brings it to feel VERY familiar to the legendary Code Black from the Storm catalog. It's a great skid-flip piece for later in a block that brings a lot more control to the picture than most balls in the category, and mine is a permanent fixture in my travel bag!

    The Rubicon's design intent is to give you an Idol like shape. The UC2 clears the front more than its solid counterpart just like the Idol Pearl did compared to the Idol solid. For me, the UC2 is slightly smoother than my Idol Pearl. With a small intermediate diff, the UC2 is an asymmetrical piece and that's probably accounts for the small difference. I took the UC2 to the Players Championship with me and I couldn't put it down in the later games. On the flatter patterns, my angles had to be super steep. The UC2 cleared the friction I saw in the front part of the lane and gave me good motion off of the dry to the right down lane. Once they broke down on Shark, I was able to shim it up the hill from left of 4th arrow. I had other symmetrical pearls and they just didn't see the lane correctly for me. They were quick off of the friction in the front part of the lane where the UC2 blended them slightly more because of its asymmetry. The versatility of this ball can't be overstated. I think this ball, like the Idol Pearl that preceded it, will be a homer for a majority of bowlers no matter the style. Expect this ball to be stronger than our Idols and WildStreaks but weaker in the front part of the lane compared to the original Rubicon and Nuclear Cell.

The mildly asymmetric Rondure core combined with the latest eTrax (Enhanced Traction) pearlized coverstock makes the Rubicon UC2 a pin crushing monster for your arsenal. Let's take a look! The "mildly" asymmetric Rondure core introduced with the Rubicon is a game changer for a straighter and more down and in player like me. I found "mildly" asymmetric to mean the best of two cores in one, if you will. This core rev'd early in the mid-lane with the precision of a symmetric core and simply continued to roll like a freight train down lane! Starting from fresh oil straight up 7, to after the transition where I was able to look 15, the Rondure core was impressive all night. This hard rolling asymmetric core explodes at the pocket and maintains a strong continuation through the pins regardless of entry angle and keeps rolling its way through the pin-deck. The eTrax Pearlized coverstock completes the UC2 quite nicely. Out of the box, the 1500 grit polished surface performed smoothly all night. On fresh oil, the cover cleared the heads easily and maintained a strong turn off the pattern. The eTrax pearl cover read the mid-lane section throughout the night with a smooth and predictable motion and stayed consistent. As the shot broke down I appreciated this cover's ability to blend the deteriorating condition without "jumping" off the spot. I found the eTrax "pearl reactive cover" to be exactly as written. It's a pearl but it is reactive! In closing, I found the Rubicon UC2 to be a hard-hitting, strong rolling weapon! If you're a more down and in player like me who counts on that extra hitting power, look no further. This ball is the right choice! The Rubicon UC2 belongs in your bag!

    The newly release Roto Grip Rubicon UC2 features the Rondure Core which is wrapped around the latest version of the eTrax pearl cover. I drilled my UC2 5.5 x 5.5 x 1. I was excited to drill this ball because I absolutely loved the Idol Pearl and since the original Rubicon has reminded me so much of my favorite Idol, I couldn't wait to throw this one. After throwing this ball for awhile it stood out against everything else. It is a lot smoother than say an Axiom Pearl and Trend but has a little more backend shape than my iQ Tour Nano Pearl. Compared to the Rubicon, I actually have to be deeper into the oil with it because the cover stock sees the friction so well and doesn't slow down. I believe the Rubicon UC2 will be one of the most versatile balls in my bag by using it on the fresh and those early transition games!

    For the UC2 I drilled 50 x 3.5 x 30. The purpose was to go long and turn hard in the back on our 44 foot pattern. I would put this ball as slightly strong than the Axiom pearl due to the asymmetry of the Rondure core. The original Rubicon was a smooth solid where the UC2 has a shaper backend motion. This ball does work well when the backends have dried up or its able to be played on an outside line on fresh oil.

    The Roto Grip Rubicon is the brand new asymmetrical pearl from Roto Grip. this ball features the Rondure Core wrapped in eTrax Pearl. If you liked the first Rubicon, you will like the UC2. It fits right in between the Nuclear Cell and Idol Pearl. It will come into play in league most of the time and for tournament bowlers, it will come into play around game 3-4 of a block. This ball does not stop at all. For me, it has always gone through the pins very well and never deflects, which is a great thing to see out of an asymmetric pearl.

    The Rubicon UC2 impressed me immediately after throwing the first time. I was wondering how this ball would fit in while having the Storm Trend, Axiom Pearl and Roto Grip Idol Pearl. This ball was one step above all the mentioned balls and gave significantly more down lane angle than them as well. Although, the Rubicon UC2 was cleaner than most of the balls above, it had a more distinct backend motion on all test patterns. On the house pattern, the amount of angle on the ball actually forced me a little further left with my feet to start than I anticipated. Even on the breakdown, the UC2 angled so hard that again I was forced further left than I have been accustomed to. If you bowl on a house shot that is more even across the lane than a typical wet/dry house condition, this ball is for you. On a 41ft sport pattern, it was difficult to use on the fresh because of its sensitivity to the backend. However, when the pattern broke down and I needed to shape the ball on the heavier volume, this ball really shined. It allowed me to be more in my comfort zone and just feel relaxed that the ball was always going to hook down lane. I believe on heavier and/or flatter oil conditions, this ball will be most useful. If you want to replace an idol pearl, this is it. If you love the Rubicon Solid, this will compliment it well. There a lot of positives to this ball on the right conditions. Don't be afraid to take off the polish on the ball to tame down all the angle. Adam Chase Storm Staff

    The Rubicon UC2 is great! It only took me 3 tries to get the desired reaction out of my original Rubicon, with each one I drilled being stronger. The fairly weak Intermediate Split (weak asymmetry) is something that is new to the RotoGrip line up and new to me as well. After having a chat with Tim Mack about the Rubicon, I decide to shorten my PSA to PAP distance considerably. If you are a Dual Angle person, I shortened my first angle (drilling angle). This was a game changer! I used that same layout on the UC2 and OH MY. This is such a fun ball to throw! The covers on both Rubicon's seem to be a little weak so I can see myself hitting this UC2 with a little surface, just to knock the shine off of it. Its an amazing complement to the OG Rubicon in case they are a little too slick to start the night off with the pearl. To me, these balls are absolute house shot Killers! Layout for the UC2 is 4x5x1.5 or 35x5x30 Other balls that are seeing some love at the moment Rubicon- 35x5x30 Trend-50x5x30 RST-X1-50x5x30 Hyroad Pearl-50x4.25x65

    Ball Review: The compliment to the original fan favorite Rubicon is here featuring a cleaner Coverstock (e-trax) attached to the staple Rondure core. What I liked about the UC2 is it's response and continuation down lane when it sees friction. It's very quick when it responds and the continuation is unparalleled. This ball is a great option to have on the first set of transition after the solid or asymmetrical read a little too early. The Rubicon UC2 is the strongest symmetrical pearl that I currently have in my bag. The Rubicon UC2 will be a must have for the competitive bowler.

    After drilling two Rubicons, I was very excited for the pearl version, the Rubicon UC2. I just threw it for the first time yesterday and I'm already impressed by the motion. The cover is even cleaner than I thought it would be, giving me a nice compliment to the Nuclear Cell. In my YouTube ball review you will see how the Rubicon UC2 is a little bit cleaner through the fronts than the Nuclear Cell, giving it a sharper down lane motion. This ball will be great for house shots and for any time you need to move left with your feet. Oh and have you seen the colors of this ball? The pink lettering on top of the shiny, dark cover looks great! I might have two or three of these, it's that good!

    If you like the Rubicon or Idol Pearl, but need a little more pop on the backend, then this is your ball. It kind of reminds me of my SnapLock from a few years back. It is cleaner than my Idol pearl and little more angular. This ball reaction helps to kick those corners out when the oil starts to carry down and the lane transitions. If your benchmark ball starts leaving you flat 10's/7's the UC2 will be a great ball 2 option. I feel like any style bowler can use this ball. Its easy length will be great for slower speed players but high speed players can pipe it up the outside. The medium speed players can baby arc it or move in and bounce it off the dry. This ball fits perfectly between your medium ball and your big hook/heavy oil ball. Ron D'Ambrosio Storm Amateur Staff #StormNation #SquadRG

    Roto Grip's new addition In the HP3 line is the brand new Rubicon UC2! This brand new ball is the pearl version of the Rubicon! This features the eTrax Pearl Reactive Coverstock wrapped around the Rondure Core previously seen in the Rubicon! The Rubicon UC2 that I drilled is pin over my bridge which is about 4 1/2 inches away from my PAP with the mass bias next to the thumb! This provides me a cleaner motion through the front part of a lane with a good smooth continuous motion for a shiny pearl ball which is unique! It's cleaner than the Rubicon but also will be smoother than an Idol Pearl! This is a very unique shape that is a must have in your arsenal! Get yours 1/29/21 at your local pro shop!
