Agreed - but some part of me can't help looking to make everything as 
conductive as possible "just in case". My primary reason for using 
silicon-bronze washers with the brass nuts is the similarity of metals 
should prevent galvanic(?) corrosion that can set in with dissimilar 
metals. Then again I'm not a chemist by any stretch so may have that 
wrong.
