Well I got fed up of the tiny juice channels on kangertech's subtanks RTA decks. They're so narrow. So I decided to get out the dremel and widen them. And the results are good. It's a much better vape now. It wicks far better with much thicker juices and allows me to go a much higher wattage. You can see from the first photo one channel done so you can see the difference. The second photo is the finished one with both done. I've done three tanks so far - two ST Plus and one Mini.
