A Q of 10???  What did they wind it with -- toaster wire??

If an unloaded Q of <100 would suffice, then it seems that the 
space-wound geometry with a small toroid would be the best approach, 
in order to achieve a lower L/C at the lowest cost. Why add extra turns
to the sec, if doing so only forces the addition of a larger toroid to 
compensate?  The extra turns do not add extra voltage.
