I've been vaping for two years and have considered going back to analogs countless times because of similar issues. There really hasn't been a hassle free cartridge system. They leak, clog, taste burnt, mute flavor, etc., etc. I tried every cart and tank i could get my hands on. The best setup I've found is a protank with the airflow control from a protank3. Good flavor, good vapor, and it's easy to rebuild coils if you don't want to buy them.
