Steven,
I hope that you did not take my post to imply that you did not know what you are doing. I understand your thoughts and you sound a lot like I do. I design precision measurment systems for coating applications, and even with our most basic systems we measure to 1 micron accuracy. So believe me I know what being fussy is all about.
I am really pleased to hear that this worked so well for you. After all being happy with your system is what it is all about. Just for your interest the wire I used in my system is made by Belden.
Happy Listening!
Cheers
John.
