I knew someone would make such a comment...

Despite tongue in cheek, I do have a good reason for not replacing 
the TH7s with C31XRs. I did look into doing such a thing about 3-4 
years ago. After modelling the antennas, turned out the C31XRs had 
LOTS of interactions (in my 1 tower SO2R configuration) with the 
heights available for the lower antennas on my tower, and would be a 
performance loser.
