Well, I have been vaping for 3 years, and since I am proficient at rebuilding both RTAs and my RDAs, along with DIY on my juices for over a year now, I am guessing that in most circles, I wouldn't be considered a noob. Yet, I own several subtank minis, and I usually use the OCCs versus the RBA section. Why.....because there are times when I am lazy, busy, etc and it is easier and quicker to pop in an OCC coil, versus re-wicking or re-building. Now, with my Delta IIs, I admit that I use the RBA section versus the pre-made coils.
