I don't have any of those particular nodes to give you an answer.
wrt 128 nodes... I understand that RJ limited the pixel count based on node type. some strings consumed more power than others, and so (for example) he limited the TM1809 flex strips to 120 pixels, and he limited the smart string nodes to 128.
That limiting is driven by the node selection in the SSC utility.
unfortunately (!?) the same selection drives color order (RGB, BGR, GRB, etc.) so, if you have a new string type that follows the same color order of the flex strips, you'd pick flex in the utility -- and you'd also get the 120 pixel limit with that choice.
I believe that only 120 and 128 have been applied as limits -- it would be one or the other.
