I recently upgraded from a Jobo CPE-2 to a CPP-2. Wow. What a difference in size and capabilities. <p> Anyway, for those who use the expert drums, do you use the drums to wash your film? How confident are you? I would like to get away from using a lucite vertical film washer if I can, but I am concerned as to whether or not the jet tube that Jobo makes works ok. Also, how long would you suggest running the washing process? <p> Since I bought the CPP-2 unit, a 3006 drum, a 3010 drum and other accessories used, no manuals were supplied with them. <p> Thanks in advance for all responses.
