Good Evening Alan,
I have used the 10 oz. mix, but it's been with 4 × 5 T-Max 100 when I do night shots processed in a rotary drum. It works great in that situation with a little seat of the pants time adjustment based on how I interpret the contrast of the scene. I suspect that, with perhaps a slight increase in developing time, it would be OK also with Tech Pan in a tank, but I've never tried it (probably never will, either, since locating Tech Pan now would be problematic and expensive).
