OK here is my fabulous "improvement". It is so simple it only took me 
4 or 5 hours and a few blown high power ultrafast diodes and TVS's. 
In the end I settled for this. Only 4 components, two of which are red LED's.
Simply, it reads the polarity of a spark. The led closest to the 
spark is negative ie the spark from the toroid on the left is a 
negative leader.
They then alternate polarity far further than one can see as a spark.

Guess how I did it. ie what are the two other components.

Photos of the strike which is a negative leader and the alternating 
polarity of the ringdown are at the bottom of this section on my site.
