Hi Hal,

Sure send the large image my way. It's always better to look at the 
original. I'm pretty sure I understand the particular streamer you are 
referring to on the left side. Steamers do not always go horizontal. 
They will follow the a path of least resistance if it's out there to 
follow. They can bend and change coarse at any point. Granted, there is 
a "usual" breakout direction and path, but as the coil is running, the 
charged and heated air around the terminal will change it's path or 
sometimes actually cause a more predictable path (the initial breakouts 
are sometimes very erratic).

Take care,
Bart
