Shot a roll of 35 mm last week and developed it in D-23 replenished. It's not quite 400 speed, but the negs print fine. It seems to be very much like an early Tri-X - grainy, but with decent definition. It's not going to be my regular film, but I bought some in Prague and brought it home to try. The 200 is another thing entirely. A bit contrasty, great definition, and develops well with Beutler. That could well become my slower speed film of choice.
