Yes, I understand what you're asking but "the t-grain developers like DD-X" implies that DD-X is specific to "t-grain"...which it is not. I was just trying to disabuse you of the notion that DD-X was somehow specific to t-grain [films] because it certainly is not. I don't know enough about TMax developer to comment on it. Bottom line is thatDD-X is a modern developer that is well suited to just about any modern B&W film...not just Delta and TMax.
