Hi, I have been off cigarettes for 6 months now. I have a Russian 91% (1.03 ohms) and a nautilus (I used the replacement coils that I think are over 2.0 ohms). I run them on a Sentinel MI6. The reason I went to the Sentinel is because I wanted a battery that lasted all day. Anyway, I am not a cloud chaser, just like good flavor and a throat hit. I have used a ZMax and IMotion in the past but there were times when the power levels would change on their own if I was not careful and would end up burning wicks etc. I thought it might be user error until it happened more than a few times. Anyway, I was just curious if it would be beneficial to move to a VV/VW. I hear the dna 20/30 are good if you can get your hands on them. Again, I vap because I wanted to quit smoking and now use it like I would a cigarette. Any help is greatly appreciated. Thanks. Mark
