So after testing out crappy pen style vapes I decided to upgrade to the kamgertech Kbox mini, and then to the mutation 5x plus as my nodded tank. I'm still new to this but I did do a coil looped 9 times and created the rda. Runs at about 1.7 ohms, and I've learned to not use too many watts on it. About 15-20 max. I have some questions on some things, what kind of juices run best in these, I got some 80/20 juice lemon cookie, and other craft juices, and one was 6mg nicotine, the other 12mg. The 12 hits harsh even in the subtank. What's the best vg mix that works for mods, and can I dual coil this rda? Curious to see who uses this unit and maybe some tips for it
