Delta 3200 is NOT Tmax 3200. It's very different. Still may not be what you want, but it certainly has a strong cult. Use it fresh. It spoils worse than slow speed film. Gets fogged from sitting around.
I use DD-X, but that keeps the grain in check. Of course it's still very apparent. But if it isn't enough for you then you might try good old D-76 or even Rodinal.
