OK so the other day i received the scar from smok. The original coil really sucked so i rebuilt it with ekowool and 30ga kanthal. Hit better but still sub par. Both coils equaled out to .8 ohm so i though to myself, i should be pumping out way more clouds. I noticed it was drawing really hot too. Like burning the back of my throat hot with little vapor for what a dual coil .8 should pull. I pulle dout my trusty drill and 1/16th drill bit and got to work. I drilled out the top cap and the base. The base is what feeds the two air ports under the coils. I didnt touch those because drilling out the base to the bottom chamber did the trick. A 1/16th hole barely fits between the two o-rings but if you have a drill press or a steady hand(my method) you can do it no problem. No more hard hits and plumes like a choo choo train. Just thought you guys would like the know.
