Hey Bish, nice build you made there buddy. In reality what you did with the dual kanthal/silver wire isn't a micro coil but just a different dual coil setup and a nice one too. The true micro coil is by definition a relatively high ohm coil (1.7 ohms or so) but behaves like a sub ohm coil. In other words it heats up unusually easy for it's ohms (because the wire is touching) and obviously produces much more vapor that other equivalent ohm coils.
I tried exactly your setup down to every detail and it really works great if you're into a warm vape on the iatty. It works much hotter than other dual coils I use in the iatty but it produces heaps of vapor
As always, very nice job pal
