I have a SmokTech rda coming in the mail tomorrow, my first true rebuildable. I have heard some good things about it. I also get to practice my skills with rebuilding to my personal preference. I bought 34 gauge kanthal wire and silica wick. I am not fond of how the RDA comes with like 8 wicks in the chamber (seems like overkill). So I might tinker around and tell you what my favorite setup is. I tend to like dripping more so than tanks and cartos. I can change flavors of juice often without having to empty out and restart. I will let you know how my efforts go with rebuilding and also with the RDA Octopus.
