It's kind of funny because I started doing this a really long time ago and it always has worked perfectly and I just figured everyone was doing it to break in a new Atty, especially LR's of any sort and 306's but just all of them, I have never gotten that burnt taste now for maybe 7-8 months since I've been doing this, it definitely is the way to go for breaking in an Atty for sure, the entire bridge, wick, and under the cup get a full flavoring blast of what ever juice you decide to use.
