Well I just took apart and rinsed/cleaned my vivi mini nova with hot water, dried and screwed on the atty head I built earlier this week that was soaking in my tupper ware container. As I suspected, first pull tasted clean as can be. There was no break in period at all. I think I will try this method for VN's from now on since I have an extra head for each of the 2. It must have been soaking for 4-5 days, so it definitely had fully expanded, absorbed.
In theory you can do this with Drunker coils as well, if you have spare ceramics! It seems like it'd be messy and not at all fun to push soaked wick through the feed holes (I've tried.. it sucks).
