I like my dual coil.
I
vape at 3.7v and keep it full; just can't fight my direct drip tendencies.
I've run a few ml
through dual coil and it is still clean.
The vapor is warm, flavor clean, TH powerful, clouds excellent.
Great when dripping is not convenient.
Love joye 306 atty too.
Great for flavor changes, etc.
I switch back and forth depending on mood.
