Well Mike I being the lazy type on some things I tend to order pre wired Ds since I have some friends who make em and to repeat I can be a little lazy..usually I'll get a few each of orange ,blue black gray and yellow kinda covers most my bases...but as a modeler I'm always looking out for "stuff" that might be useful like wire etc.. from your post I'm not sure if their referring to the color or the material your using but having seen an awful lot of your work, I never saw anything that would make me point and say look at those plug wires and aside from the colors I buy, I've seen 1:1s with green, purple,red etc. Pwires sooo..hey if ain't broke don't fix it!!
