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.
