should be plenty different. I dont know how everyone's artillery came out of the box, but mine were not with a heavy polish, the equation will be. The equation also shares the core of the heat blast, a very smooth even ball, that gets down the lane well. The core/cover should give the look of a heat blast, just gets down further and has more pop in the back.
