I was curious how often you all replace the wick in your clearomizers. I have iClear 16, iClear 30 and ProTank. I've been cleaning them every couple days with water to keep them fresh, but in a week I have noticed the iClear 16 isn't hitting as hard as I would like. They are the ones I use most since they are easy to bring when Im out of the house. Also, any suggestions on where to get cheap replacements, especially for the iClear 16? Fasttech doesn't carry them. I'm considering just getting some CE6 from them since they are so cheap that I could just throw them out rather than piss with replacement coils in the 16. The Protank and 30 are still fine since I use those tanks as my "treat" when I'm home relaxing.
