Greg,

IMO, readily available Qs of 75 to 150 are plenty good enough and 
higher Qs of 300 or so would give no benefit.  TC damped oscillations
never get the chance to build up to a high dynamic Q value in an
operating TC.  (Am I missing something?)

The efficient results that coilers have obtained using cardboard
secondaries (with a Q of 10) seems to support this view.

I agree that the often ignored area of power supply to TC matching, 
is an intriquing and important subject that warrants further research 
efforts. 

Regards,
