Thanks Gerald for the info on Phenidone, but we all have to admit that there is a mighty difference between Tech Pan and ImageLink. Tech Pan 'gets it all in' and the other does NOT. With Tech Pan all you have to be careful with is development. Most of the other formulae presented are really standard MQ types having both metal and HQ.
I do not (obviously) have the definitive answer here and maybe that definitive answer is in the negitive. I have YET to see this ImageLink presented 'getting everyting in' for a contrasty scene . - David Lyga
