K4VX is a very good friend of mine (the author of the article).  However, 
common sense and experience tells me that his computer models might have 
been either over simplified or the computer couldn't handle the model 
correctly.  I wonder what you experts thought of this article?

I used unbroken guys on the bottom set of my 15M stack.  The SWR on the 
lower antenna was different (higher) than on the upper antenna.  When I 
switched this guy out for phyllistran last fall the lower antenna exactly 
tracked the top one's SWR curve.  You can't convince me that unbroken 
guys are a good thing.  But you can't convince me that broken guys are 
either.  The only thing I trust for non-interaction is Phyllistran.  I've 
heard stories about broken guys affecting antennas adversely also.  From 
guys that knew what they were doing.
