About a month ago, when I first got the Tornado-T, I commented that I was having trouble with proper wicking and the resulting dry taste. I vape VG. After seeing some of the responses, I fiddled around and came up with what seems to be a good fix to the problem. I bought some PG liquid and have discovered that a 80% VG, 20% PG mix (20 drops VG plus 5 drops PG) works very well. I get a good amount of vapor and have not had any problems with dryness. Also, there has been no leakage of any kind that I have noticed. It doesn't quite measure up to direct dripping on a LR atomizer, but it is an acceptable substitute on those occasions when constant dripping just is not possible. I hope they come out with a LR version of the tank atomizer soon. I would really like to give it a try.
