Hi, I recently bought a wismec presa and a Cool Fire 4, have been using my itaste vw and aerotank mini and protanks 2 and 3. But taste buds have finally cleaned up and I've started to enjoy fruity and desserts.I additionally bought a delta 2 and kanger subtank, but don[t like higher wattage or direct lung hits. I want to try a rta that's easy to fill and provides good flavor and TH. Top fill would be appreciated.
