Proximity effect isn't a factor unless conductors are very close
together -- I suggest you review the previous postings which explain it..
As far as "better", the answer is that it probably doesn't matter, since
either a wire or strap can usually be pretty easily made large enough to
make loss negligible in those applications.

Proximity effect is when you are too close to a directional microphone
and the bass is accentuated. *I think you mean mutual coupling.


Wrong one of the several meanings, Dave. See fourth entry under
http://en.wikipedia.org/wiki/Proximity_effect.
