It's his second V2, same problem. I also have multiple V2's and no problems. My wicking is not always the way I want it, but still it doesn't leak. Well it leaked once, I closed the AFC all the way before I filled it and then that is when it did leak. After that I always make sure it is full open before I fill. Before that I used to get very minor flooding after a fill, now never. He did try with the AFC full open, but for him that doesn't work either. I found with my Berserker that if I do the opposite of the advice and leave the AFC open it doesn't leak, close the AFC and it makes a mess as soon as I open them. But it still does flood even with the AFC open so I went back to bottom filling the Berserker, just too easy and 100% dependable to waste my time trying to do it any other way.
