I've never been into sub ohm, nor will i get into it. I have a 1.8ohm micro coil with cotton wick in my protank right now, and a 1.5ohm micro coil in my rebuildable.
My question was in the mere calculations.
If i were to make a quad coil id shoot for .8 ohms.
Understood. My limited knowledge of multiple coils seems to think that each coil added effectively halves the resistance. So I'm thinking .8 quad = 4 - .2 ohm coils? Yeow. You could cook a roast with that kinda heat.
