I'm 6 months vaping and new to rebuilding. Here is what I've found so far. The flavor and vapor quality I prefer comes from an nautilus mini with the bvc coils but I got tired of buying so many coil heads. The goal was to recreate the N mini experience in an RTA and I got close enough by duplicating the ohms, draw and watts I use on the N mini in a Kanger sub mini RTA. I tried the same with an Egrip RTA and got equally satisfying results. To reduce the air flow on the Kanger I expose only part of the smallest air hole. On the egrip I restrict the RTA air supply by wedging a peice of aluminum foil in the air hole so it won't fall out.
Vapers rave about the great flavor they get from low ohm lung hits. That's not my experience. My atlantis is gathering dust for now. May be my tastes will change but for now I'mm old school, lower wats, higher ohms, tight draw, mouth to lung hits. Then again, I've always had a knack for being out of step with what ever is mainstream.
I guess you're just another Tootle Puffer...........
