I loved when the Rogue Cell came out and I still use it sometimes when there is a bit more volume.  I agree- bring out a hybrid and a pearl.

I would like to see the theory core and cell core in the edge cover

I still throw my Mutant cell.  I hated this ball when i first threw it.  I put it away for almost a year.  Took it back out and it was still squirty at first.  Now after a bunch of games on it, the ball is so controllable and still has a beast of a backend.  I guess i just needed to change the cover when I got it or let a bunch of games get on it so it would just  a little more tame.
