I have no experience with amidol.

As for your question about Pyrocat-HD and HP5+ many people are

reasons pyro staining and tanning developers give better results than
traditional developers. For more information see my article on pyro
developers at http://unblinkingeye.com/Articles/PCat/pcat.html
