Aw common Ron , don't take your bats away we just got started.
Could you please explain technically how Potassium Bromide will change the grain structure therefore causing the post flash tones to go a different colour.. I would give it a go but I am just a lowly printer and do not want to talk scientific nonsense.
PE is right if you use the same dev for both baths there will not be a tone change and I only use two baths to inflict silver clumping radicalization tone effects. (post development, fix and wash) using bleach sepia , gold and selenium components to tone the print.
