It seems as though this question could be bandied about here ad infinitum.
There are a LOT of knowledgeable people on this reflector, and I don't wish
to speak ill about any of them, but with so many opinions, I think the best
advice would be to find a PE who could rule on your specific installation.
That way it's HIS career, insurance carrier and reputation on the line if
something goes wrong, not yours.
There are too many variables -- and with all due respect, a new one seems
to pop up with each of your rebuttals -- for even the brightest minds in
Washington state, or Florida, or Michigan, or whereever, to knowledgably
pass judgment on your installation.
