Staples 12ply .4×.1 Nichrome80 ribbon / 40g Nichrome80, also 6 wraps and 3mm ID, dual coil = .11 ohms... this build works best for me at 168 watts and a preheat (power curve). I probably should note, the coiling up part will give you nightmares unless you give it a quick run of the torch before you coil it up. For claptoning 40g Ni80 around your ribbon stack, use the ziploc technique... just let the spool spin itself around inside a half-closed ziploc bag that's standing upright in a box on the floor, and also use magnifying goggles (a plastic pair of─3× magnification─reading glasses also can work... I actually even use two pairs stacked together and find the correct distances for a sharp focus).
You can't vape on this build with just a pair of LG HG2s. For a dual 18650 regulated mod, you'll want to pick the LG HB6... so, because the battery life on that will be like shittier than shit, grab yourself a triple battery mod like the Reuleaux RX Gen3. (Or better yet, grab yourself the RX300 because, at 168 watts and using a power curve, I can vape the four batteries flat in like only four and a half hours─or even less if you pay me to do it.) As for which batteries to pick with the RX Gen3... without using a power curve, but with the voltage cut-off set to 3.2 volts (you can use ArcticFox firmware for that), 168 watts divided by three batteries (RX Gen3) will translate to just below the CDR of the LG HG2, which is 20 amps─so that would still be OK safety wise, BUT... with a power curve that peaks at 128% (mine does), you'd need the Sony VTC5A, the CDR of which is 25 amps (and then you'd still need to set the voltage cut-off to 3.2 volts for safety... you can, and should, do the math yourself). Bottom line, if you really want to try this at home, the RX300 equipped with four VTC5A batteries will always be your best friend because, then, the ma(t)h won't hurt as much.
