Oh hey! You beat me too making a topic on this. I have basically everything Doctrine and plan on picking up a Black Diamond set when they launch into retail on the 10th.
I've actually been approved as a Ninja for Ninja Division, one of two in Texas I know of so far and the de facto one for Austin and Houston atm, so I'll even be at Texas Games Con on Friday at the very least doing demos with my friend's Cerci speed circuit and my Doctrine. Should be interesting!
