I have this really sweet DC tank from MyVaperStore.com...but I also use a Lavatube. The built in safety doesn't work well with dual coils..sort of locks the voltage down around 3.9 or so and I prefer the 4.5 to 5 range. So I'm switching back to single SR/HR cartos. I still want to use my tank though. So what is the best way to cut one of these down so it still looks and performs well?
