I am also an electronics engineer and have found both chokes and twisting to be essentially useless, from both a theoretical aspect and a practical one, on servo and battery leads. Now twisting does neaten (is neaten a word?) up the wiring a bit.
LOL Rodney I don't know how many times I've heard about twisting servo wires preventing interference.
Its great for phone and network cable, useless for servos.
