18-20" isn't bad at all for a 180 Watt coil.

You're right about the toroid size--there's a
practical limit as to how big an object a Tesla coil
can charge.  If a bigger toroid makes you sparks
smaller, you've exceeded the limit.  Just for grins,
you might try a smaller top terminal--just to see what
happens.

Careful tweaking might get you up to 22" sparks.
Really though, if you want bigger sparks, you need
more wallplug power.  Try paralleling another 6/30 NST
and increasing your tank cap size.
