Fasttech has some small cartomizers for around $2 each. I was thinking about getting a few for trying new juices. That way if I hate the juice I'm not risking a coil and having to clean the tank between flavors. I'm trying quite a few new flavors right now to find something I like as well as Ace 4th Street so I don't burn myself out on it (best flavor ever, IMO). I've also had some juices I didn't like so much steeping. I thought I'd check with some of you before wasting my money. Thanks!
