I am looking to switch paper developers. I am not happy with the Sprint developer I have been using for the last year. I prefer neutral tones and the solution must keep for a while because my darkroom in 30 miles from my house. I am currently looking at either Adox Adotol NE or Moersch ECO 4812. What can you tell me about these developers. I am currently using Kodak Polycontrast but I will soon be switching to Adox MCP 310 and eventually Adox MCC 110 for more serious printing. Any suggestions.
