Malcolm,

I would agree wholeheartedly.  I have Greg's coil on three or four of my
tapes thanks to Jeff Mullins who sent in his video tape and shared a
number
of runs of Greg's fine coil with us.  As a two coil system, I would say
that
Greg Leyh's system is the most efficient that I have ever seen.

As to Golka's skills, I would agree and stated as much in a more polite
way
in my original post.  Golka did most of his work before the "modern era
of
coiling" and was, again, just miming Tesla's 1899 work.  Still, his
sparks
are the longest recorded sparks I have physical evidence of regardless
of
skill and power level.

I have long said that as the spark length grows, the power required goes
up
incredibly and dramatically.  This is regardless of skill level. 
Whether
the builder uses a giant toroid, giant coil, or not.  Anyone who is
observant and is used to working over 5-8 Kva will agree with this.  In
low
power coils, 300 watts per foot is a good rule of thumb.  To about 20
feet
of spark, this rule ups to about 1KW/foot!  Beyond 30 feet, another
world is
entered entirely.  These rules of thumb assume better than average
skills.
