Kevin, as I understand it, a helical primary overcouples, a flat primary
undercouples, and a primary with an inclination is in between.  Larger coils 
will probably want a flat or inclined primary.  Helical primaries should be
okay for smaller secondaries.  I have a 4" diameter secondary and use a
helical primary.  Another person I know with a 4 inch uses an inclined primary.
The inclined primary would probably be your best bet.
