Greek, Greek, Greek. lol.
I haven't tried carto's yet. So, anything to do with them sounds foreign to me. Once I read about hole punching, finding the right number of holes, etc. I got intimidated.
I have cleaned my larger nova tank. It then continued to leak into the battery even thought everything was nice and tight...maybe too tight. Then I read something about pins being pushed...Greek...Greek...Greek.
I haven't cleaned my mini nova yet since it is still new. However, my main complaint there is lack of flavor and the insane amount of juice it goes through...even at low voltages. Who can afford that kind of juice habit? I used to wonder about people that said they went though 5+ ml per day. Now I know how. No more satisfaction...just less juice.
I just got the T3's yesterday. They are the ones giving me grief. I like them because they go through less juice. However, they also have much less flavor, and are very "airy". I have read about covering an air hole. That just leads me to a burnt juice flavor. Not to mention the difficulty I had after cleaning. Lost an entire sample bottle of AiV juice before it was said and done. Not happy about that at all. I really wanted to enjoy not eating that cupcake. ;-)
Faylool- I agree with you completely. The learning is difficult. Especially when the things people are commonly referring to are things you don't even have a general idea about. And then there are all of the internet abbreviations. I know what LR is. I have no idea what 35 and 45mm length ss replacement cartos are. I really don't know much about cartos at all. Just a very vague idea of the concept. I don't mind learning, but the trail and error of this lifestyle change has quickly cost me more than what I was smoking. Between supplying my husband and myself with eGo Twist batteries, back up batteries, wall chargers, usb chargers, disposable tanks, cases, Vivi Nova tanks, Mini Nova tanks, T3 tanks, replaceable coils, etc...I have broken the bank. We won't even begin to talk the several HUNDRED dollars I have spent on all of those yummy juices I want to try. Better stock up now. They need time to steep you know.

If I spend any more money, my husband may just kill me in my sleep. And...I still haven't found a tank system I am satisfied with. I guess the search is endless. At least going by everyone on ECF that is still searching looking to buy something "better."
I am quite sure that the answer to real success is some combination of saving money by rebuilding coils/wicks yourself. I have always been terrible with hands on things, whether it is woodworking, mechanics, or anything else. It just isn't an area my talent shines. Add in little bitty pieces, and I am soooo out. My husband is great with those things, but this whole things hasn't peaked his interest. He happily uses whatever new toy I bring home in regards to esmoking, and makes the best of it. Kind of like dinner. Whatever is on the stove is good enough for him. He instantly understood the mechanics of how everything works. I still don't have a clue. I just try to follow the advice and get by. Mechanics have never made any sort of sense to me. I am sure it is quite simple. It is just lost on me. Battery, coil, wick, juice, vapor, mouthpiece. I get the concept. I just get overwhelmed and lost in the details.
