So... I'm a newbie at vaping so I still have a lot to learn. I rely on it to stop smoking. So far it's working wonders for me but I have a major issue. I like to puff on my mod (vamo) quite a bit, sometimes for 5-10 minutes at a time for maybe a few times an hour. The first couple minutes the taste is good but after a bit the hits almost taste burnt. Am I overheating the coil? If so do I need a higher resistance coil? Right now I'm using a dual tank clearomizer with two 3.6 ohm coils to give a 1.8 ohm total. I also use a single tank dual coil clearomizer that came with the vamo that is a 2.5 ohm coil. I don't get the burnt taste as much with that one but I like mixing my juices so I like to stick with the dual tank. Any ideas?
