1.0 works for me. All my mods can handle that, easy to get with 28 to 32 depending on how fast or slow you want them to fire. I've found microcoils give me frequent dry hits so I prefer LARGE 2.4~3.0mm wraps. I'm using cotton but twisted 3mm silica can function too. Actually 6ml last me two days so I don't have to change them that often.
Gonna try 2.4mm with 28 gauge. How many wraps should that be for around 0.8 ohm? Dual coils of course. should be around 8 wraps on each coil right?
