JGL:
Sorry, one other point I forgot to mention. You said above:
Looks like the powers that be decided to move this to the electrical forum so I doubt I'll get the responses from the larger audience I was hoping for.
I say, "Exactly." I should have used your words to provide a frame of reference for mine. I should have begun my post above by showing the above quote, and then transitioning into what I wrote by saying, "If you were hoping for a larger audience.....".
Again, I think you're thinking about all the right things, including and especially polling members of all forums for ideas.
Now I'll be quiet.
