I'm playing around with rebuilding a Vivi Nova v2.5. I don't really have any materials, but I do have several used cartomizers lying around. What I'm presuming is that inside a Boge carto, which has a vertical style coil, the black insulated lead wire that runs up and then back down to the actual heating coil would have to be non-resistant, correct? Presuming it is, if I stripped off the insulation then I would have a bunch of free NR wire.
