What have you guys tried that works? I'm up for either a different cart or a mod. I tried the E2, but was very disappointed with weak flavor out of them. Also tried pulling the wadding out, but it wasn't much different. I want to use my V4L batts. I'd rather have a cartomizer, so no atty, but I'm up for getting an adapter if needed. My goal is to find something that I don't have to fill as often. TIA.
