Thanks for the info.
I am a little bit surprised as you are the only having replied to this thread. It seems as the Ilford warm and cooltone developers are not very popular among the darkroom printers. The only test of these developers I found was the one by Mike Crawford in the March 2006 issue of B&W Photography. The latter was however of no great use to me. I posted the same thread in the German APHOG.DE, but I got absolutely no reply at all. Strange, isn't it ?!!
By the way which Moersch developer will you use to replace the Ilford Cooltone.
