    I love how hard this turns left. It has a smooth motion but turns hard.

    Roto Grip Rubicon UC2

    Roto Grip Rubicon UC2 Cover Stock: eTrax Pearl Reactive Core: Rondure Core My review of the UC2 will be different than any other you will read. When the UC2 was released I was very happy with the mid-strength pearls in my arsenal and was worried about overlap, so I drilled my UC2 for very little flare. I drilled my UC2 60x5x50, looking for a urethane like roll with a little more punch through the pins. Long pin to pap layouts are similar to short pin to pap layouts for me. Anything 5" or more or 2" or less will have very little flare. With this layout, my UC2 looks just a touch stronger than my Fast Pitch...not what it was intended to do for most people but it's something I didn't have in the bag at the time. It's not for everyone but it is a useful situational ball for me.

    Roto Grip Rubicon UC2

    Posted by Brian Watson on May 27th 2021

    The new HP4 ball in the RG line is the Rubicon UC2. RG took the very successful Rubicon and added a pearl cover (eTrax-S20 Pearl Reactive). I drilled my with the standard pin up above fingers and MB an inch right of thumb. When first throwing the UC2 I was like wow a lot of backend reaction. Super clean and angular downlane. A "Quick Ball". On the fresh it was really too much down lane, where the UC2 shines is later in blocks or 2nd or 3rd game of league when the heads burn up a little. I have added a little surface to cover to help slow it down a little on sport patterns. Very popular balls with the PBA guys and league bowlers. Definitely a home run from the Schlem and Utah guys!

    I’m a big fan of the E-trax cover and could not wait to throw this beast. First love the colors on this ball really looks good going down the lane. Now lets talk about the ball motion really clean through the fronts really picks up mid lane and boy does it go on the backend and through the pins with authority. This ball def meet by expectations and I am loving it .. Grab one today you will not be disappointed

    Rubicon UC2

    Ball Specs Cover Stock: eTrax Pearl Reactive Finish: 1500 Grit Polished Core: Rondure Core RG: 2.49 Diff: 0.052 PSA: .011 Layout: 35 x 4 3/4 x 15 Drilled the same as my 900 Global HB Intensity and Revival, I was looking for the same shape but more snap. With the slightly lower rg and higher differential I could easily see more of an angular motion at the breakpoint than than the HBs. After 21 games I am able to use the UC2 more as a game 2 ball after the Intensity and before the Revival. I was pleased with the pearl covers performance during breakin period as pearls usually take a longer time for me to use consistently. Overall a very complimentary ball to the solid or first ball out the bag depending on your preference. Pick up one at your local VIP Proshop or 12 IN A ROW PROSHOP at JIB Lanes

    Rubicon UC2 - Ball Specs Cover Stock: eTrax Pearl Reactive Finish: 1500 Grit Polished Core: Rondure Core Layout: 65 x 4 1/4 x 40 RG: 2.49 Differential: 0.052 Intermediate Diff: .011 Review The HP3 line Rubicon UC2 has the Rondure Core which was developed to increase the ball’s motion throughout the lane with the absence of the balance hole. The UC2 is very clean through the front part of the lane, reads the midlane well and turns the corner hard on the backend. As a mid to low rev player the UC2 eTrax Pearlized cover stock will flex its muscles during transition especially on longer house patterns to help get the corner pins out. I tested this ball on 44 feet typical house pattern with a lot of down lane transition. This ball will be in my bag for league and tournaments. This is a great ball for all levels of bowlers.

    Rubicon UC 2

    Posted by Curtiss Rasnic on Apr 27th 2021

    LANE CONDITION Length:41 Volume:Medium Type (THS, Sport Pattern etc):THS COMMENTS Core: Rondure Cover: eTrax-S20 Pearl Finish: 1500 Polish RG: 2.49 Diff: 0.052 The Rubicon UC2 is everything I expected and then some. For me the UC2 will be a great THS ball or a later in the day tournament ball. Its so clean down the lane, but once it hits the friction it just goes. The backend reaction is really where this ball shines, as you can just keep moving left with your feet, the ball drives harder and harder off the dry. I was a little worried that for me this ball would go to long before making the turn, and leaving a lot of corner pins, that was not the case. The pin action is something that is most impressive with the UC2. This is a ball that will be in the bag for a long time.

    Roto Grip Rubicon UC - e-TRAX pearl coversotck - Rondure Core 1500ab grit with factory polish - layout 55 x 2 1/2 x 55 The next step in ball motion is here - the Roto Grip Rubicon UC2. The Rondure core is a edgy core design, making the core asymmetrical, but very close to a symmetrical after drilling. On mine Bret at Bowlers' Supply laid it out to miss a majority of the spikes on the core to keep the integrity of the core in place. Even with short pin layout, the ball still went down farther down lane then the Roto Grip Idol Synergy and the Nuclear Cell with longer pin layouts. The "wobble" that the ball produces allows it to pack a powerful punch off of the dry and packs power through the pin deck. Used the ball on older HPL with a 44ft THS with a HUGE amount of volume and the ball rode through the front part of the pattern like a ninja sword slicing through watermelons. Best additional for a step up from the RST X-1 and the Idol Synergy. Thanks to Bowlers' Supply, Inc and Vise Inserts for their continued support and teaching more about this awesome game of bowling!!! #SquadRG #3Gshoes
