Un-Terry, Brian, 

Regarding the smoothness of operation, maybe the many
turns used in some ballasts is acting like a series resistor to
smooth out the current, and dampen bad resonances, 
especially during async gap operation.  Variacs in contrast
have such a low series resistance, so this may allow such
resonances to occur.  It would be interesting to add series
resistances to the variac set-ups to see if they smooth out.

When I used a variac as a ballast in my sync coil, I had a 
different problem.  The coil ran smooth, but horribly 
in-efficient.  Instead of drawing 600 watts, it drew 1200
watts.
