I am not yet the most knoledgeable on the theories of the Tesla Coil yet 
(but I am getting there), but I have one idea about the 1/4 wave 
conflict.  Why not just do a simple test.
  Now - please dont jump down my throught or anything - but do tell me 
if there is some problems with my idea.
  Build (if you dont have on already) a Tesla Coil that is designed so 
that its length of wire on the secondary is equal to the 1/4 wavelength. 
This will only work if you have a larger toroid you can also run the 
system with. Measure the maximum spark length produced by your 1/4 wave 
Tesla Coil.  Then put a larger toroid on it that brings the frequency 
below that of when it was equal to the 1/4 wavelength. See if spark 
length increases. If it does increase this could mean many things but it 
comes down to the simple fact that it worked better than it did when it 
was equal to the 1/4 wavelength. I know that many other factors can 
change but what does it really matter if you trying to get the most 
spark length - and one way gives you more spark?
  For example, I have tried this. I have a small 3.5" diameter secondary 
that has 500' of wire in it.  Running it at around 400kHz (1/4 wave 
equals 616') it has almost double the spark length and several times the 
power as when I run at the 1/4 wave frequency. And yes, the coil was 
fully retuned for all experiments.
  Constructive critisism is welcome.
