letting it soak over night, or even 30 mins sounds insane to me ><
I rebuild and fill and it soaks at max 30-60 seconds before I start vaping and have had no problems. I use cotton balls and just the tiniest bit of it to get through a microcoil. I don't get leaks or dry burns (unless my protank is completely empty). I actually end up burning off a wick when I want to replace it (so far I've only replaced when I decide to try a new coil setup, or if I want to change the flavor).
