Does anyone know the difference between the RCP tracks and the official Kyosho kits? RCP supposedly made them for Kyosho but I can't find concrete information about it.

Also, it was mentioned earlier in this thread that the mini96 track can be made up of two wide L tracks. Is that correct? Below is a link to the Kyosho L track.

How about the the extension circuit? Has anyone ever used it or know if it's worth purchasing along with a couple of wide L tracks? Primary use would be DNano and Mini Z.
