So I've started to dabble into sub ohms, I got a 30amp sony vtc4 battery a k100 mech and a trident rda. For the most part I get some pretty good hits off of it but every now and again I get some really really harsh hits like it's burning my wicks even though ive juiced me up decently to the point it's overflowing out the air hole. I'll replace the wick when I get two or three harsh hits and it'll be good for about the next day when I start getting harsh hits again. I've got a .3 ohm single coil setup using cotton ball wick, going to try adjusting the coil a bit more and seeing if that will help, any suggestions? Or am I just not changing the wicks enough?
