My experience with dual coil gennies is that they're pointless (
IME), the Strata may be different as the design sounds more intricate than the others I have tried but with my Hellfires I found dual coils to take twice as long to get up to temp, ate the batteries twice as fast, used twice the juice and bizarrely no real benefit in vapour production or throat hit.
I had two 2.6ohm coils for a final 1.3ohm, compared to a U wick with a single 1.3ohm coil the U won, hands down. No problem with effectively two wicks feeding that 1.3ohm coil, never a dry hit, heated up instantly and my batteries lasted much longer. Oddly similar TH and vapour production too, Hellfire is not Strata though, I am expecting them to be completely different animals so dual may well be the way to go with them, dunno.
As far as a 16340 version of the Strata is concerned I'd be very surprised if one is made, as much as I love my P16 the 18XXX's are pretty much the standard for mods now. Weird as a few years ago the 16340 pretty much kicked off the whole "big battery mod" thing, now (with the 14500) it's the smallest battery size for a mod that's really viable. I live on 18350's these days as I like smaller mods but I can notice the difference between an 18350 and a 16340, seems a bigger difference than you'd think..
Does it seem like a year since the first Strata tease to anyone else either? I can't wait to get my sweaty paws on one of these
