First, I don't have a throat hit or vapor problem - those aren't an issue at all. I've been doing this for just over three weeks now. Letting the atty break in and moving to blue foam made a world of difference in those areas. Also, I'm mainly using the cherry flavor. So here's my problem. Some days I have great flavor all day long, but most days I have basically no flavor at all. I don't get it. I feel I've tried everything. New foam, cleaning the foam, new atty, cleaning the atty. When I think I have it solved, it winds up that I don't. Now when I direct drip, I have no problem. Is THIS why people direct drip? Why should this make a difference? Meaning if I'm getting the throat hit and vapor, shouldn't I be getting the taste? If not, where'd it go? And why might I have an entire day of great taste in between? Thanks everyone. Your'e all invaluable.
