Thomas, we both run replenished. But good call b/c THAT was one of the big steps I made in getting my negs closer to what I've seen him do. But still, there's something more. I know he uses a slightly buffer dilution though, which would cut about %40 of the time in developer, and that's why my brain clicked by what Mr Carnie had written about silver migration in the highlights. In fairness, the person I'm referring to is literally one of the most accomplished B&W techs in the world, so the bar is set high.
Granted, it's not day and night, looking at the film, more subtelties. When I run up to a higher CI, my TX shoulders off. When I've seen his TX, even denser, the shoulder looks like TMY (that is: not one).
