I used to rebuild my protank and protank mini heads and also used rayon for wicking. That gets tiring very quickly, especially when you are doing fancy builds on an rda / rta that produce much better flavor than any tank, and much easier to build on. That killed all of my usefull willpower to continue rebuilding my micros for my tanks. The performance is quite a bit better than factory, but imo it is just too much a hassle for the little performance gain you get.
Don't get me wrong, I used to take my rebuilt protanks over to my buddies and they would marvel at the taste and performance compared to their stock coils. But I think we all get past that point with time, especially if you go the route of rda's.
I built my first dual micro setup on an rda, took me 2 minutes, was so easy, nice big deck to build on, no fiddling around with tiny rubber insulators and wicking inside of a space the size of a pea. And I even have tiny hands lol. And fired it up, and never looked back at any tanks until the Nautilus. I use the Nautilus very rarely, but I would never take the time to rebuild it as the stock bvc heads are decent for as much as I bust it out. If I wanna build, I build on a dripper that takes much less time and hassle, and get much better performance and flavor that messing around rebuilding any kanger / aspire head.
This is what I am using now. Simple dual twisted macro build wicked with rayon on the Magma. Great airflow adjustability, and the flavor knocks any tank out of the world.
My suggestion is, if you like to rebuild your kanger heads as I used to, than I recommend trying out an rda. So much easier to build on, and WAY better flavor. In fact, the Magma with a 1.1 ohm build on my iStick around 18 watts crushes any Nautilus as far as flavor goes. But when I am out and about, I don't like to drip. And that is why I have an Orchid v4 rta on the way!
