as far as the cores go if that is true...the only difference between the epx core and the super trooper core is the flip block on top of the epx's they both use the rock on core's shape so the reactions would be SOMEWHAT close
now if it had the original trooper's core thats a different story thats just the offset puck
i agree with you strider this wasnt a very good showing of the epx
ive seen what this ball can really do...when thrown on the right shot its amazing
