Report Card Review: Roto Grip UC2 Bowling Ball by Luke Rosdahl

here is my report card and take on the roto grip uc2 bowling ball

Roto Grip Rubicon UC2 Is a Backend Monster But Consistent 

Thanks for joining us for another video, this is a report card for the Rubicon UC2.  Details are the refined etrax pearl coverstock, just etrax, there’s no year of the formula associated with it.  The core is the somewhat new Rondure core which is a mild asym, 2.49 RG, .052 differential and .011 split or intermediate differential in 15 pounds.  Same RG and diff as the Ikon core in the Idols but with a mild asymmetry that really just improves the torque down lane, makes it firmer.  The UC2 is a backend monster, and I do have an update to one of the numbers at the end of the video.  Very clean up front, very flippy down lane, but this is absolutely the most consistent big backend ball I’ve ever thrown.  I can always count on it to hook and finish, if it doesn’t, I’ve thrown it terribly.  Angel and I both have softer speed, and having a ball like this that we don’t feel like we have to throw or try to push down the lane that will also boom like this really makes us comfortable.  Usually when a ball covers this many boards, it’s because it’s just strong, my UC2 covers the same amount of boards as my Incite for example, but I’ve gotta remember to stay firm with the Incite because even though it’s a fair amount smoother than the UC2, it’s got a lot more traction.  Side note, I’ve recently begun to find those two to be really good compliments, the on lane shapes and zones they like to play are really similar and they allow me to flip traction and shape with the same general ball motion.  If I need more dig, it’s the Incite, if I need more length and shape, it’s the UC2.  

Rubicon UC2 Ratings 

As mentioned earlier, I made a slight adjustment to the numbers.  7 for hook, 7 for length, and I moved it up to a 10 for backend strength.  It was previously tied with the Nuke for biggest backend ball in the catalog, but it’s actually quicker, plus I can’t really imagine more boom than this.  I’m sure they could make it happen, but it would probably be more inconsistent and wouldn’t ever make it out in the world, so I think this will be the high watermark for friction response and I just can’t believe it’s as consistent as it is.  Thanks for watching and may the strikes be with you.
