Saw the United Revolt in action last night. It was pretty strong off the spot for the bowler (high rev and speed - think EJ Tacket). The bowler had a little too much friction for the United Revolt and the ball was a tad unpredictable. Moved to a Jackal Ghost and was able to control the break point well.
Also, one of my bowlers was using a Code Black with decent success. Started with the Phaze but it was burning up a tad because of the required launch angle. Moved to the Code Black and was able to get a better reaction at the breakpoint.
Of the two, the Code Black seems to start up a bit sooner and be more rounded. If you are looking for something to react stronger at the spot, then I would say the United Revolt. Depending on how you approach carry down either could work. If you like to bang it off the dry and force the reaction, then the United Revolt looks good. If you like to start the ball early and make sure it reacts some, then the Code Black would be the ball I think.
But man, that United Revolt looks pretty strong and is pretty similar to the Code Black. Last night's assessment could be because of the differences in bowler styles and the newness of the United Revolt.
