Thanks, Kurt, I appreciate your insight.  Good technique about making the 
coils identical and just
flipping the wiring.

You know, while I've always wanted a twin system, watching the video 
earlier this your that you made of
your twin really made me start to plan for it.  The general scale of your 
system and power level works
well for a guy stuck inside of a house.  Thanks for documenting your coil.
