I spent a couple weeks researching when I decided to start vaping to figure out what equipment to start with, and after almost 2 months, I STILL have no interest in rebuilding ANYTHING. I would no more build my own atomizer or whatever than I would build my own lamp, because I DON'T KNOW WHAT THE HELL I AM DOING. I see plenty of people talking about how easy it is to rebuild, recoil, etc., then I look at the instruction video or whatnot and think to myself, "Yeah, but that basically goes in my MOUTH." and I get a visual of Daffy duck with his bill blown to the back of his head by an exploding cigar. People have to have some common sense with these things. It was clearly stated pretty much everywhere I looked what "entry level" really was, and if people choose to ignore that, well....there's only so much you can do. After 2 months I feel like I'm ready for a VV/VW unit, but rebuilding? No thanks. My Protank's doing me just fine so far.
**Disclaimer: the following rant is not directed at you Jack**
I started just like you Jack... took my time READ EVERYTHING religiously, and finally, after talking with my SO about the pros and cons, decided to move into a device like a VAMO (shes a never-smoked-in-her-life'er, and is so supportive that I'd be an

for not including her in the decisions. She's been behind me 100% with vaping, DIY'ing liquids (lemme tell ya about doing some research...those stickies have a LOT of info to process!), and she reads CASAA info as well. She's my rock, and the reason I ask "should I?"
The ONLY reason I got my phoenix and IGO-L was to have an easier test bed for tasting the DIY's. I knew I could very well end up like Daffy , so I stick to 2.0 ohm coils (give or take a small margin, still not a pro). Could I rebuild my EVOD and Protank heads? Most likely. Can I buy them for dirt cheap? yup. so why bother with the rebuilds? I already clean them and get months of use out a few heads, I see really little point to spending a little bit to have fresh heads when these die off, especially when I am mixing my own liquids.
Knowing your limits and what you personally are comfortable with is the biggest thing we can all do as humans. Just because "Vapeshadydawg" over on reddit said what he does, doesn't mean that you, or myself, or Ocelot*, or anyone else on this forum has to run out and try to be "awesome like him"... (apologies if there REALLY is a vapeshadydawg)
If you want to push boundaries, then do so safely. Know what can happen if that battery shorts, know how to maintain your gear. Know what to use in what, and if you're asking people here about which batteries to use in a mech mod so you can vape sub-ohm, then you certainly don't know what you're doing, and you seriously need to re-think the idea.
Vape safe. That's all I'm asking.
(*Besides, Ocelot has Bobo... nothing is more awesome than BoBo)
