That is what the contact micro coil replaced...that is 2mm silica wick and a very spaced coil. With those, you really couldn't move to even 28g wire, because as with a mech, the wattage would have been way more then what we were vaping , or to low a resistance to what the only 2 regulated devices were able to fire. So micro contacts were implimented to obtain a better way. Also it sucked to wrap wire around silica and then attach to posts (cotton was the answer along with a sturdier coil).Oh, yeah, I wasn't even thinking about those. Something like this. Never occurred to me in this discussion. I've seen 'em, but it was before my time. I did a swap with someone, giving them my Prime for a KF2, and it had one like this one still in it. I'm sure you've done them similarly, back in the day.
