Hey Leo, that must be me. When I was working I would get calls from the special circuit people about something that was not right. I used to wire the stuff in the central office and then rewire until it worked. Sometime I would let the engineer of the circuit know what I did. Some times I didn't. But, this one gal would call me and if I could answer her problem. Of course I would say I have answers. This one night she called me and gave me the question. After a few minutes silence I finally told her I didn't know. She replied that was not an answer. I informed that was the answer and we were both up the creek. Together we finally got the circuit working again.
In the early days when I was trying to fly combat, everyone was using .015 lines. I liked .018 as they held up better. Have fun, DOC Holliday
