May ask why exactly an ASRG is bad for an NST?

Although a non-synch rotary would be a bad thing for a NST powered tesla
coil, non-synch (asynchronous ARSG) spark gap will
provide great results when used with PT or PDT powered tesla coils.  In
fact, I get much better and more interesting results when using
an ARSG over  SRSG with my coils due the ability of being able to vary
the
output etc...

Ed Wingate, Terry Blake, myself, and others have built ARSG powered
coils
which are highly successful and big output coils.
Especially Ed Wingate's magnifier which can easily throw some very big
arcs
indeed!!!!

However, on Ed Wingate's magnifier, he using a combination ARSG / Series
gap
which is also fan cooled providing very fast quenching for the
magnifier.
Its definitely the most impressive and elaborate spark gap system I've
seen!!!
