First 18650 vtc4 sub ohm build, need help.

[nikki from mars]

I tend to dual coil.... which obviously doubles surface area as halving the ohms... for single it wouldn't give much surface area... so if you're not happy with that you'll need to use the thicker wire. .. but just depends on your preferences. .. I am happy to dual coil to 0.5 ohms 6 wraps... don't go lower ohms particularly. .. am often around 0.7 to 0.8 if I single coil.. was just saying as others have that it heats up quicker... as an alternative to single coil that isn't heating up for ages...oh and I wrap around a screwdriver but what specific diameter it is I couldn't tell you off hand... am getting a coil jig soon so in future if anyone asks i can be more specific. ..
