That's the thing steelbender.  I went to vape to stop analogs even though I haven't really smoked one in a couple years, I was doing nicotine lozenges for that long without tapering off and it was bad.  The starter set I had was pretty crappy, so I figured why not get something a little better, so I got on here and started doing some research.  Got a PT2 with an ego c twist.  Since then I've gotten the Zmax (this is all in the last 3 weeks or so).  I've also gotten a Davide tank that I like the air flow on, but with the Kanger coil heads, it's leaking juice.  I haven't tried to figure out why really yet. 
Up until yesterday, I had no interest in building my own.  It wasn't until I saw SuperXDrift's videos on how to do it where I thought I will give it a whirl.  It's definitely turned into a bit of a hobby and I'm not contemplating getting a mech mod, but I think the goal is to ultimately stop vaping (or nicotine) even though I'm only on 6mg now.  I do enjoy the whole vaping experience and love the bigger clouds.  I could probably do without flavor too, but I'm having fun trying to find an ADV.  I've spent more in vaping equipment (i.e. batteries, APV, charger, juices, tanks, coils, etc) than I would have in analogs in the same timeframe, but I'm really enjoying the whole process.
Side note - I lowered the coil a little and it seems to have helped with the heat and I turned up the zmax to 10W and no problems with heating up the coil quickly.  I am not getting a whistle from the airhole when drawing and I get some snap/crack/pop sounds.  Is that about normal?
