The one thing that is good about CAD is that you are more guaranteed to duplicate both sides of the form "exactly", subject to distortion of the paper itself, the joining process of multiple sheets, etc. If you can get it all on one sheet, so much the better (probably beyond most of us, although some people do have plotters at work).

Plotting a half form allows another potential point of error introduction in that one must flip and align over the centreline. Not only that but you may not mark the form in the identical location corresponding to the other side of the form, thus another point of error introduction is introduced.

All that being said, I plotted by hand, and I have access to a plotter large enough to plot the station forms full-size. And as someone on this board once said before, you'll never get it perfect, and the deltas will probably not impact the end result too greatly (paraphrased).
