This thread is exactly what I was looking for tonight, so thank you all!!  I just want to be sure I get it straight.  (I have Kanger Mini Protank II's and EVOD)  SO, first has anyone done this on a EVOD with success?  I MUCH prefer the Protank, just tastes a million times better.... but I'm broke!  So, just pull out the wicks from the bottom and thread through some cotton?  How much do you leave on each side?  What about a candle wick?  I used to make candles and have a bunch of cotton wicks SOMEWHERE... anyone try that?  And can do the same cotton on EVOD?  Thanks in advance!!
