If I were calling the shots, I would build something that would sell, SO I would get on the epoxy band wagon, build a gas mask core ball with a mild epoxy cover that would cover more boards than anything on the market by about 5-7 boards.
Then I would sneak into the back room and formulate a ball that I would not let others have.. a MILD MILD urethane covered vibe. O yes, revs, control and hit... ahhh thats the rub.
Then MAYBE I would look at producing a gasmask clear spare with full details on the gasmask.. ya know the look of the respirator the whole 9.
