I have a subtank mini,kayfun 5 and a few other single coil rda tanks. Is there anything new that can deliver more flavor than the subtank mini or kayfun 5? I’m after flavor and prefer a tight DL like a kayfun 5. I’ve tried looking for some of the older single coil RTA tanks but many are discontinued. I just wondered if there’s anything new that can deliver flavor as consistent as subtank mini or kayfuns?
