Greg,
In my projections, I let the impedance "drift" from 126 ohms for a small
coil, to 22 ohms for the large coil. This was empirically based on a
linear projection of two small coils I built, rather than on any theoretical
underpinnings.
Maybe I'll try your 15 to 25 ohm primary idea and see what happens.
