Personally I find you workflow a bit odd and backwards. To get the best out of Dehancer, you should make use of the whole developing/printing process it provides. So the first thing is setting the print stock, cause it makes a huge difference in contrast. Than I choose my negative, and after that I do everything else within Dehancer. If you do contrast/exposure etc. first with Resolve nodes , you limit your self, and you get a less clean image, since Dehancer (that uses a different math under the hood) has to fight those nodes, an it is getting muddy really quick.
