primary voltage again



I have been wondering for a long time about the input voltage on a tesla coil
(primary
side of tesla coil secondary side of power xfmr). I have heard several times
that
power is the determining factor in spark length. If this is so, will you get
the same
results with the following?

5kv-at-2a, 10kv-at-1a, 20kv-at-.5a, 50kv-at-.2a, and 100kv-at-.1a.

Why does not anyone use 5kv or 50kv? What is the highest voltage anyone
has pushed to and what were the results? I asked before and only heard from
teslakd-at-primenet-dot-com (Thomas Kelley). his work was with 85kv-at-?ma, he
said the results were about the same as a normal tesla coil, but with more
electrostactic properties (not sure what that means).
But he was using 22 .01uf caps in series. What if he had used the same value
cap and primary turns that you would have with a standard coil setup (for
a given xfmr power and coil frequency)?? I would like some real life feedback
on
this with detailed explainations from everyone that has the time.
