Anyone use this rba I trying to produce big clouds like on you tube. I was also thinking of doing a dual coil if possible and if it is possible does this drain battery quicker?So Far I have drilled holes in atty which does produce more flavor and great TH I usually do a 5/4 or 4/5 wrap (sorry not good with the lingo yet) and get around 2.3-2.8 ohms with 32g kanthal and silica wick. Ive included some pics to show what I have.
