I missed it. Why are you sorry????

Haha. When I posted my answer you already had found the answer. You actually wrote it down in your post, but I, for some odd reason, skipped that part of your post, Black
In relation to your question, 2 things come to mind when doing that.
1-Flooding (obvious) which eventually might go away due to channel being closed and you vaping the excess juice.
2-Possible INITIAL leaking thru the bottom. Can be solved by blowing excess juice thru main channel.
Other than that, I might actually give it a try. Just for giggles. It's just that I find opening and refilling through the top cap so easy that I have never even thought about filling my tank thru the mouth-piece.
