Ignition cable lenghts

["Ph.J.Aeckerlin" <j.aeckerlin@tiscali.nl>]

Thanks to everyone who reacted to my question about cable lengths.
It is interesting to note that the manufacturer of my new ignition, 
123Ignition, recommends the use of resistor core silicon ignition leads. 
They state litterally  "Do not use solid core wire, these send out a lot 
of  electromagnetic noise that interferes with electronic devices."
