Marc,

I read your mail too quickly before, and answered differently on
the list, but yes; your idea above seems like a good one.  By keeping
the frequency and inductance about the same, you'll be controlling for
those parameters.  This comparison should show if a wider coil is
better or not, and how much better for the same general F and L.
