I just got a Reuleaux 2/3 with the smok tfv8. I'm using the coils. My question is what is the best setting to start with I started with 45w 3.67v but it gets hot and pops and drains the battery quickly. I have it at 35w at 3.19v right now and it works. Is that a safe setting to use. I'm just now getting into building coils etc. so any and all help would be great
