Of course 1CANN/gram is the optimal choice, however I don't know how achievable and sustainable that will be. I personally think 10CANN/gram is the better choice and more sustainable in the long run.

Even if the economics are  sound, you've gotta fight the idiots and the traders to keep the price there, and that's a hell of a lot harder @ 1 CANN than it is 10 CANN.
