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
