out of curiousity what resistance are you at when you are running at 9 watts?Good for you! You can only try....your body will quickly let you know if it is going to work for you or not. I am a true tootle puffer, still sitting on about 18mgs (depending on my diy) and 9 watts, but I am happy with that for the while. After smoking for 38 years - vaping has got to be better!
