I started vaping with a couple Evods and a Mini PT2. The Evods worked well except they'd randomly leak badly, and the PT2 wouldn't wick 50/50 liquids very well. Flavor wasn't that great compared to Aspire BVC coils either. I keep reading about how rewicking with cotton solves those issues and gives much better flavor, so I got out my Mini PT2 and some leftover coils. Followed these instructions Stop throwing away your protank coils – ITCVapes couldn't find organic cotton anywhere so used "100% pure cotton" balls from Walmart. I'm getting big dense clouds, can run the coils at higher wattages, and no wicking issues or leaking. However I've tried a few different juices and they ranged from almost no flavor to about the same as the stock wicks. Any ideas why I'm not getting the great flavor I keep hearing about?
