Subohming tends to be too hot for me. I like cool vapes. I know dual coiling would help with that but at some point it gets ridiculous farting around with all these setups. I'm using silica on a 2.0 ohm coil on the Provari and it rocks my world. I've tried a myriad of other setups and get no additional benefits. Just me. I used to like monkeying with stuff. Now I just want crap to work and don't get into the screwing around as much.
I hear that. Get it to where you want it & maybe try a tweak here n there along the way. Ever since I started twisting this coil I just make another one long before I actually need it. I just changed coils yesterday & I already have one formed, hanging out on the drill bit in my pencil tray. I do like the cotton wicks though. I don't try to make them exactly the same (using cotton balls) but I know about how much I need & just go for it. The margin of error is plenty big enough that they turn out fine.
