Re: 6ga wire vs 1/4 tubing for 900W coil primary?

I would be very surprised if the primary guage has anything to do 
with primary strikes.  Stranded wire only increases the effective 
surface area if there is no way the current can come to the outer 
surface of the bundle ie with individually insulated strands ie Llitz 
wire. Primary strikes in my view are mostly due to the toroid configuration.
Here is my double toroid with no hint of primary strikes or corona 
despite sparks 3 times the secondary length.

Here is my 18 inch diameter coil with a primary made of 14g wire 
(much smaller than 6g). Admittedly underperforming but still 5 foot sparks.
