I would go for and RDA, as it will soon change, how about a squonker with a Dead Rabbit RDA and a squonk pin? I was Instantly, building coils , making my own juice and dripping RDAs as soon as I started vaping. more due to cost. I Have a good few coilheads, TFV12T12. My first mod was a four battery SMOK GX350, with a Cloud Beast King after a week of vaping. I have cleaned coilheads in ultrasonic bath and re-used them, using bioethanol mixed with water. Never as good as new though.
Did you know you can take apart coilheads and re-wick, or put in new coils? Neither did till last week!
