One other thought: when you convert to RBG, the size of the file increases.
A greyscale image does not have the R, G, and B channels, and is thus much
smaller. It is certainly more economical to save the duotone, which is just
a greyscale image and a small .ADO file that desribes the curves.

It may well be that Photoshop creates some kind of temporary intermediate
RGB file, which it sends to the printer and then discards, but once you
convert to RGB and save the image, you have lost the original greyscale
information. It seems to me that the best way to retain the original image
(in case you want to present it differently later, with a different duotone
curve set) is to save it as a duotone.
