Been vaping for eight years, but not much into mechs anymore. My last mech was a Great Lakes Vapor and that lasted five-ish years. Ran dual 16340s. Old school.
My favorite at home setup is the Steamcrave Titan on top of the Steamcrave PWM. Dual coil 4mm 26ga Kanthal, 6 wraps. I set up a quad coil yesterday but the airflow sucked.
My on the go vape is a Dovpo Topside with an Asmodus Bunker, single 4mm 26ga SS, 6 wraps.
Started wicking with rayon, pretty happy with that once I got it dialed in.
I have a bunch of other mods I use too. Don't use fancy coils though, I only vape thick, sweet juices and they gunk up too fast.
I keep it pretty simple.
If I were to go high end I'd probably get a 3D printed box mod. I already carry too much shit on me, trying to stay lightweight.
Edit: Correction, my last mech was from Super T Manufacturing, I think it ran an 18650. They went under years ago, which is a shame, they were really one of the first to come out with mechs that were REALLY well machined and made in the US.
