Well, after a suitable period of investment (moderate money but more sizable time) into the grand experiment of RDAs/RBAs, I find myself heading back toward regular, old-school 510 atomizers.
The financial toll was about $150 for everything, not bad at all considering that I now have a stock of 16 rebuildable atomizers---two A7 Minis, two Igo-Ls, a couple of Phoenix-style SS mesh-wick tank clones, and ten dirt-cheap clone RDAs (from FastTech, of course). Six of the ten are KTS YK1 mini-RDAs, which are Cyclone clones, and quite impressive for being so inexpensive. I converted three of the YK1s into bottom-fed atties by drilling micro-channels through the silicon insulator surrounding the positive pin on the 510 connector. They work just as well on my bottom-feeders as the A7 Minis, which are designed as bottom-fed.
Also acquired along the way were two 100-ft. spools of Kanthal A-1 wire (29ga and 32ga), plus numerous kinds of wicking material---twisted silica, braided Eko-Wool, raw hemp twine, and cotton rounds.
Ive become fairly proficient in winding my own coils, either regular coils of 32-gauge Kanthal, or micro-coils using 29-gauge Kanthal. The learning curve on that wasnt overwhelming, although Im sure my current skills dont put me in the top echelon of coil-winders. I didnt explore sub-ohm vaping, but instead stuck with resistances from 1.32.5 ohms.
By last week's peak of the six-month-long experiment, I was using RDAs on five of my eight bottom-feeders. Yesterday, however, I replaced all the RDAs with the same regular atties I had always used before beginning the grand experiment. Why?
Three reasons:
1. In the final analysis, wrapping coils, threading wicks, and rebuilding atties is not enough fun. Oh, its not dreadful, but its more work than pleasure, and anything in vaping that stops being fun or pleasurable and starts feeling more like work has a very short half-life for me.
2. The experience of vaping with custom coils and wicks on an RDA is not that much better than vaping with regular atties. Sometimes maybe 10% better, but thats outweighed by other times when its not better (or even worse), and also by the extra amount of hassle in dealing with re-wicking and rebuilding coils. I understand and accept that RDAs/RBAs are a revelation for some vapers who now swear by them, but that just hasn't been my personal experience. And no, I haven't tried a Kayfun or Russian and don't intend to spend the 23 bucks on the Kayfun clone from FastTech just to find out.
3. Basically, I like regular atomizers. I like how they draw and how vapor feels and tastes with them. I also continue to use and enjoy a selection of cartos and clearos, which continue to comprise the bulk of my vaping. Vaping with atties is reserved for my bottom-feeders and for testing new juices.
Anyway, thats my decision for this week. Next week may be different.
