In commercial labs, the only manual sheet processing that I did was in sinklines, racks and tanks. HC110 w. replenishment for B&W. I never even see this method mentioned anymore.

In my recent attempts at 4x5, I'm using an old JOBO 4x5 tank and reels because... well... I already had one and I can't afford enough of that precious dark to tray process. (Except late at night). Seems to work fine.
