So, it has been a little over week and it is going really well (not great yet though). On day 7 the wife and I tried an analog, still had a few in the house. Ugh, went into the trash! I was using that nasty thing?!? 
There is still so much to figure out. I do have a few questions for those more experienced (which would likely be any of you. I will give you an idea of where I am at .
I started off with an EGO 510 kit and really like it compared to what I had tried. Yesterday I almost bought a LT VV mod. Started reading a thread and got very lost in the 1.0, 1.5, 2.0, 3.0 versions and which was which. I was about to pull the trigger but as I read more I found that the 3.0 version was really a 2.0 and that the 1.5 had serious problems (I think that is right). I went back to looking at the Provari and pulled back thinking jumping in that deep that fast was a bit much. I got a drip tip in, aluminum, and I have to say I dont care for it much. It gets warm/hot quickly. It is not major problem, but it does point out that I need to figure out what works for me (and my wife) before I spend a bunch of money. I am sure it is a great device but I hardly know what I am doing now so I have no base to compare from. Anyway, I needed a few extra batteries so I went with the EGO Twist. I will see how that goes first.
I am looking at various different delivery systems (cartos, tanks, clearomizers, etc.) and trying to figure out what is what. I ordered a Clearomizer (V2) (1.8 2.0 ohm) and got it today. Wow that baby rocks
. Better for me than dripping which I was mostly doing. Each time I try to step up its major and major fun! I also ordered a smok Tech Dual Coil 2.0 ohm and Boge 510 2.0 ohm cartomizers yesterday.
So, for my questions:
For the Twists, should I order something in the 3.0 ohm range? From reading it seems like the lower ohm units top out performance and the higher ohm units perform better at higher voltages. But for a beginner will it make that much difference?
I am interested in trying a tank, but not sure which one. Again, stuck on the 2.0 vs. 3.0 ohm decisions.
Any suggestions here are appreciated. So many options I am not sure what to try.
