Im new to rda's. I currently have an istick 30w that I use with a kanger subtank mini and love the mini rta since i figured out how to build effectively but I'm looking into getting an rda as a local vape shop vendor told me it's a better vape experience than an rta especially for sub ohm vaping. Are there any rda's on the market that would work well with an istick 30w? or should I change my mod to work better with an rda?
