Thanks for that link, Matt. That pretty much summed it up that Adobe does not support lines merge. We've come up with a couple of solutions. One is to flatten the PDF using Reader and print again with AcroPlot or create a DWF and PDF that. The DWF route is definitely the better of the two options. I have yet to test it out but it is supposed to be flawless. New software just for this is probably out of the question unless it is free.
