If you're using pads definitely take the top and bottom layer off. That skin is not good. I've used many many different types of
coils. My personal preference is rectangle wire
coils or fused clapton coils. I recommend getting an Avidartsan Daedalus kit and that way you can make whatever kind of claptons you want easily. For power mode I use rectangle wire coils and for tc mode I use ss 316l fused claptons. Thats my preference. I like big clouds and lots of flavor. I also make my own
juice that is 90vg/10pg. I use that in all my RTAs/RDTAs/RDAs.
