I'd be happy with just improvements to the existing functionality. I have a clone DNA board in a FT box mod, as well as the authentic one in the VS, and there are a couple things that I like better about the clone board.
For one, the clone board has a much faster refresh than the authentic one. As some one pointed out earlier in this thread, the authentic board refreshes so slowly that when you hit the fire button, it looks almost like it has to "think" about what the voltage is going to be. With the clone board, the voltage just flashes on. As a sub-desire to this one, I'd like to see the voltage indicator stay put after the first fire on the attached atty. It would be nice to be able to see what voltage you're going to fire with the set wattage and resistance, rather than having to fire it.
