Hello everyone, I would like your suggestions on the best rtas available at the minute. I've just upgraded my mod from the istick to the sigelei 150w which I am loving and have given the istick and my kanger sub tank to our lass. The new tank I chose to accompany my new box was the atlantis mega which is also really good imo. The only problem is I can't seem to rebuild the coils without them either leaking juice or dry hitting, and I don't want to keep buying there coils, plus I kinda enjoy making my own, I've watched and copied various YouTube videos all to no avail. So basically I want a tank with the rba section, I've been looking at the lemo and the billow. Would just like to hear what people on here think. Thanks
