Just to be clear. Crane tells you not to use solid core wires because of RF issues effecting the box. If you see arcing from the boots to the top of the plugs, there's clearly something wrong with the wires you are using. Did you remember to use dielectric grease to coat the inside of your boots?

I like the MSD wires because they have really long boots that are shapable so you can position them away from the headers. They have a real low resistance and are spiral core so there is low RF coming from them.
