ok so this is my first mech mod i ever owned. I have a sentinel m16 with the nimbus rda... As far as safety wise what would be the best batteries to get if i dont want it to explode on me and should i got with ribbon wire or regular wire. what would be the best ohms to get my coil at because i want my setup to be able to give me really good vapor production. Also what would be a good hole size for my nimbus. And last but not least.... ive seen a lot of vids on ppl cloud chasing.... i know this is a stupid question but are they inhaling all the way or at all?
