All these kinds of wire have a natural twist as they come off the spools at their factory inception...Similar to all ropes or a hoses or extension cords, theres a natural 'twist' the wire prefers. So for optimal electronic efficiency, you gotta understand the wires predisposed propensity and not force it to behave in a contrary nature...This takes some study and in field hands on practice to discern proper wire behavior to get
So on all my rigs, I run all my coil wires straight stick and tape them to the shaft at pleasant intervals, thinking if I do, the electrons will race up the wire more quicker than running around in circles in a spiral...I bet I find a few extra pennies per year on account of the speed of a straight shot cable!
(I cant believe I've put so
much thought into this, but I have!)
