Okay. I messed up some of the previous design by milling the channels smaller than I intended to. I fixed this as well as trying to implement all of the suggestions put forth. These base designs have 1.6mm channels and 1mm fins and all of the channels should theoretically have nearly indentical resistance.
I do however have two patterns to pick between.
16 nozzles with branching

16 nozzles with no branching
