The Azo I use does, especially this new Canadian stuff. It requires a negative with a little more contrast than one optimal for enlarging papers, but a lot more density.

The resultant negatives look black when I turn on the lights, but when I print them there's tone everywhere. On the old Rochester grade 2 Azo, some of my Tmax negatives require a 3 minute exposure under a 300W R40 lamp 3.5 feet above the frame.
Since I've been shooting and developing for extra density in my negatives, the shrugs formerly elicited when I showed people my prints have turned to gasps. Therefore, I'll keep on doing it.
