There is definitly confusion on these balls cores!
I would think logicly the warning sign would have the same core as the signals, vital sign, an vital energy. That was what everyone was told in the beginning as well. All the balls in that family have the same core but different covers. Why did they switch the core image on the balls page on this ebonite site to say it has the new verve core an show that after it was already out an said it was the mass bias core as well as showed that?
Where does the verve core come in or come from?
