PMK is an excellent developer for all the Ilford films. It's a tough combination to beat. You might also consider Pyrocat-HD, the formulat for which you can find at unblinkingeye.com. My guess is either would be superior to Zone VI developer.(posted 8158 days ago)For PMK pre-packaged and the chemicals needed to mix PMK or Pyrocat- HD, check at http://www.photoformulary.com/
