David,

In Dale's first post on this topic, he made it quite clear that it was 
the IMPEDANCE over the range of 100 kHz to 10 MHz that mattered, which 
quite clearly is virtually all inductance.  Further, by noting that 
frequency range, it is also clear that rise time is the issue. Further, 
I saw nothing in his posts that have emphasized resistance, they have 
used the word impedance.

Perhaps some hams don't think about wires as having inductance (or 
wavelength), but I'm sure that Dale does.  :)
