Former smoker of 20+ years. Always MTL when smoking cigs. Pretty much stick to MTL when vaping as well. Also said I would never have a box mod, but got really tired of charging my smaller tubes once or twice a day, so picked up the MVP 3.0, and it is great. Also had an older rebuildable (AGA S) that would almost always short out on me, so was only going with cartos until a couple months ago. Go myself a kayfun V4, and I love it. Usually run at .6 or .7 ohms. Just ordered a Plume Veil so I can try RDA to see how I like it. Now, just waiting for the DNA200, so I can try going really low on the ohms too. It is really nice to have all of these options, and all the different juice flavors. Just wish I had more $$ to try them all....
