Roto Grip Uproar
Right handed
Rev Rate - 400
Speed - Medium
PAP 4 up 1 1/4


The RotoGrip UpRoar is the pearlized version of the Rumble. With a low diff. of 0.030 and high RG 2.55. There was some reviews about this ball being flippy on the backend. Even with a pearl cover I personally get an earlier roll with nice continuous smooth arcing motion. With the Late Roll 51 core, the Uproar is very predictable. As you have seen Belmo use the Uproar a lot on TV this year. Very good ball for sport and PBA. But also very good option for those house shots that are a little on the light side with the oil. I drilled mine with a 5 1/2 inch pin above my middle finger. With this drilling the Uproar also allows me play on the fresh better as I don't see a big change in direction off of the spot. High rev guys will really like this ball as it is so controllable down lane when they have to get deep and open up the lane. If you liked the Rumble you will definitely like the pear version Uproar.
